What is Higgs field: Definition and 147 Discussions
The Higgs boson is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory. In the Standard Model, the Higgs particle is a massive scalar boson with zero spin, no electric charge, and no colour charge. It is also very unstable, decaying into other particles almost immediately.
It is named after physicist Peter Higgs, who in 1964 along with five other scientists proposed the Higgs mechanism to explain why some particles have mass. (Particles acquire mass in several ways, but a full explanation for all particles had been extremely difficult.) This mechanism required that a spinless particle known as a boson should exist with properties as described by the Higgs Mechanism theory. This particle was called the Higgs boson. A subatomic particle with the expected properties was discovered in 2012 by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN near Geneva, Switzerland. The new particle was subsequently confirmed to match the expected properties of a Higgs boson.
On 10 December 2013, two of the physicists, Peter Higgs and François Englert, were awarded the Nobel Prize in Physics for their theoretical predictions. Although Higgs's name has come to be associated with this theory (the Higgs mechanism), several researchers between about 1960 and 1972 independently developed different parts of it.
In the mainstream media, the Higgs boson has often been called the "God particle" from the 1993 book The God Particle by Nobel Laureate Leon Lederman, although the nickname is
not endorsed by many physicists.

Can someone help me understand why in the Sec. 3 Custodial Symmetry, Eq 45-51 he goes all the way in defining a bivector Higgs field in the way he did?
What happens to the higgs field around the event horizon of a black hole, or is this currently unknown? Does the higgs field permeate inside the event horizon? Can extreme gravity affect the field in some way by changing its properties?
Hey physics enthusiasts,
I have been reading and watching various videos, which talks about the possibility that the Higgs particle which was discovered by collisions in the large hadron collider(LHC) may not be the standard model Higgs particle. What does this mean? What is the difference...
I have heard many physicists in the media attempt to describe the Higgs boson in terms of analogies. Many seem to my amateur physicist mind to fall down immediately. One such analogy is that particles with mass interact with the Higgs field as if swimming through treacle. This is particularly...
The data from the previous LHC season has indicated that the Higgs is sufficiently heavy enough to suggest that the Higgs Field is meta-stable (False Vacuum) with the potential of an another minimum with lower energies (True Vacuum).
So the question is if the second season of the LHC will tell...
I understand that the interaction with the Higgs field (Higgs Bosons) confers mass to elementary particles such as the electron. Does that mean that interaction with an electromagnetic field (photons) confers charge to electrons? If not, what is the origin of charge? Also, how is it that the...
I have been watching a few explanations of the Higgs boson/ Higgs field. From what I can understand is that all space if filled with a sea of Higgs bosons which create the Higgs field. Is the Higgs field a property of space and does it give space energy? As more space is created with the...
If according to energy-mass equivalence, an object's mass increase as its energy increases too, then the amount of energy a particle possesses determines its interaction with the Higgs Field. How is this right or wrong?
Hi,
I was searching for some example of a theory where all the components of the higgs field are "eaten" by the vector gauge fields and no Higgs boson is left. I have just checked Georgi-Glashow SO(3) --> U(1), but they use a triplet Higgs so at the end again a Higgs Boson does appear.
Is it...
[Mentor's note: Several related threads have been combined into this thread.]
---------------------------
I read that Electron is mainly energy so it can easily travel through the higgs field. Muon has a bit more mass than Electron so it experiences friction when it goes past the higgs...
Reading around gives me some idea of WHY particles interact with the Higgs field but not How!
I am looking for a model that I can use to explain the process to my High school students. Can anyone help please.

Hi everyone,
So I've been wondering how much energy does it takes to impart some kind of effect on the higgs field. I've been trying to look for the energy the LHC generates and compare it to the actual amount of energy that it takes for the higgs field to be affected, but since this is all new...
As i understand it, at some point in the early unvierse, the Higgs field was off, then it swtiched on. Is this correct? I can't find when this is supposed to have happened, does anyone know?
I'm a high school student and I don't know much about this stuff e.g. the Higgs Field but i know that the Higgs field gives mass to some particles. I also learned that the mass of an object is relative to its speed. So my question is, what happens to the Higgs field at those near light speeds to...
It is said that the Higgs field is responsible for the mass of all particles. But the Higgs mechanism provides mass to the gauge bosons, and as far as I know the mass of the fermions is put "by hand" into the Lagrangian. Why, then, is the Higgs field responsible for the mass of the fermions?
Greetings,
I am brand new to quantum physics. By that I mean I have no idea of the mathematics and know terribly little about the physics. In fact my best background comes from the book QED by Richard Feynman. Anyway, I do know that there are four fundamental forces which have force-carrying...
Newton second law of motion states that acceleration is produced when a force acts on a mass. The Higgs field (mechanism) is the cause of fictitious forces?
is the higgs field always homogeneous, or do particles such as electrons cause it to be concentrated about certain points? Are there waves in the higgs field?
I'm pretty new to quantum mechanics, but I find the idea of a higgs field very interesting. I'm not sure if I understand the phenomenon correctly.
I was wondering what happens to the vectors of the field when a photon passes through a point in space. Is the potential of the field disturbed in...
Any "Practical," Daily Uses for Higgs Field?
First of all, my knowledge of the Higgs is limited to pretty much "Science" channel plus scientific related articles on the internet, so forgive any ignorance or misunderstandings.
I am interested in potential future applications for the Higgs...
Why exactly is it that the Higgs field is not considered a fundamental force? Since the Higgs Boson has been confirmed would that not make it a force as it's presence has been confirmed by the discovery of the boson for the field?
I'm a little confused about whether the higgs boson is the mediator of the higgs field. I haven't had a chance to study in depth the higgs field theory, but I have tried finding information from seemingly reliable sources and there are some apparent contradictions. I watched Leonard Susskinds...
Hello,
I am a layman who just read Sean Carroll's The Particle at the End of the Universe and I am trying to understand what I think is the crux of the book, the need for the Higg's boson according to the Standard model. This is my thought process:
1. The weak interaction only interacts...
Dear Physics Forum,
As I understand it, the Higgs field is a quantum field that stretches throughout our universe. Particles that carry mass (for example protons and electrons) acquire this property by interacting with the (local) Higgs field. I assume this interaction can be written in the...
Dear Physics Forum,
can anyone tell me which of the fundamental interactions is involved in the Higgs Field? Or is it a new and unique type of interaction apart from the fundamental 4?
as i understand it the higgs field is a spin-0 scalar field that gives mass to elementry particles. How is it a scalar field? I thought it was homogenous.
the wiki article on the higgs mechanism says "at a critical temprature the higgs field becomes tachyonic". Does it? If so what temprature? And how can a field be taychonic? Thanks in advance.
We know that - mass bends space-time - this is known as gravity
We also know that - (interaction with) Higgs fields gives mass to particles
Does mass/gravity bend the Higgs field as well?
How come Higgs Bosons have mass if Higgs field itself gives other thin
How come Higgs Bosons have mass if Higgs field itself gives other thing their mass?
After the Cern discovery supporting the Higgs field Which is something I have little familiarity with. Due mainly to fourm opinions not necessarily this one that had discounted anything Higgs related.
I started wondering if we do need a graviton to be the force carrier of gravity in the...
Hi guys, I've read up things on the Higgs field and boson, including the analogy provided by the CERN website. However, what I don't understand is what exactly happens as the Higgs field interact with particles. And for particles, do they mean elementary ones like quarks? Or do they mean more...
Like the question says: if a particle is perfectly static with respect to the Higgs field, can we still define mass or is mass then irrelevant?
On another note, (and if I am not mistaken) why does mass not vary with a particle's speed with respect to the Higgs field?
IH
1.) If the particle they believe to be the Higgs particle has a mass of 125 GeV, then how is it that the Higgs field itself does not have mass or react with gravity? If it is in fact the field creating the mechanism that gives everything its mass, and its particle form also has mass, why is it...
Assuming the higgs field expands at the speed of light, the radius of the higgs field (all of spacetime actually) should be the age of the universe multiplied by the speed of light. 14.6 billion (4.6*10^17 seconds) * 299,792,458 m/s = 1.38 * 10^26 meters. The spherical volume of spacetime is...
I'm just throwing out an idea, which is probably wrong since I don't have a physics degree, but I'm curious anyways. I'd appreciate anyone giving feedback. For starters, I've read that the higgs mechanism, which gives all particles mass, is a paradigm of the meissner effect for superconductors...
I suppose the title says it all. I'm not a physicist, obviously, and all I know on the subject I know from pop science. I tried Googling this but got pretty much nothing. Here's what I want to know--is there a difference between the Higgs field and the phenomenon we know as space, or are they...
So the way I understand it is that certain particles move through the Higgs field and encounter no resistance, giving it no mass. The others that do encounter resistance are the ones that have mass. But if increasing resistance means increasing mass, why wouldn't things become infinitely...
i know that they are trying to recreate the higgs boson at CERN LHC, but talking about when the big bang happened, how was the higgs field suppose to happen?
1. What is the "cause" of the field and how can the Higgs field be flat and permeate all of space or is it a property of space itself?
2. Will the field weaken as space expands? In other words, as the distance between objects approaches infinity, will that impact the Higgs field?
3...
With the recent announcement at Cern there have been many video clips published describing the Higgs field. They show heavy and light particles passing through a field and the commentary says that the effect of the field is to slow down particles and thus give them mass. The Higgs field...
Can anyone speak to what effects gravity would have on the Higgs field or vice versa? As I understand, the Higgs field exists as a non-zero base energy field. A second assumption is being passed around that this field is "constant value across the entire universe", which simply doesn't compute...
I was wondering how (or if it is known) the Higgs assigns different masses to different particles. We know that mass comes from the resistance that the Higgs field provides to particles but why are some particles such as photons able to move through without a hint of resistance, whereas...
Does the Higgs field of a fermion exclusively attract just like a gravitational field? Or can it also have repulsion? Is the Higgs field separate from the gravitational field or is the Higgs field the cause of gravity? If the Higgs field is separate from the gravitational field, then what is its...
Ok, I never wanted to be the guy posting a ridiculous question on physorg. but here it goes.
If the Higgs field is everywhere could it be displaced allowing for forward momentum perhaps creating virtual mass in front or behind an object?
At school I was taught that when any matter particle is accelerated until it almost reaches light speed, its mass increases exponentially. If this is not the case, how does an applied force continue to increase the kinetic energy of an accelerated particle without significantly increasing its...
Hi can someone explain to me how the higgs field creates gravity, or how is it related to it? I mean, if the higgs field is responsible for mass, then it should be somewhat responsible for gravity. Right?
