Higgs Definition and 674 Threads

1.In Abelian higgs model,we can come to the results that the gauge bosons acquire mass, implying the photons also acquire mass in this model；however,photons are massless in reality.How to explain this dilemma? 2.What does U(1) mean in this model?Does it correspond to some coservation laws,or...

Is higgs boson massless? Photon is massless , is photon get mass when interract with water?

i was thinking about the Higgs Boson analogy that was put forward to help describe how it works/interacts to produce mass, of a very famous person walking into a party, everyone gathers round impedes progress, high interaction with Higgs field and particles therefore high mass, and then a less...

Is highs boson a subatomic particle? If so what gives it mass. I mean if Higgs boson give mass to other particles then what gives mass to Higgs boson? Also could anyone explain how it can give mass to other particles? I would also like to ask about the light photons. How come they hon have mass...

I can understand using calculations to determine if a particular quark configuration will work and not decay instantly, but how do calculations determine which particles or fields will have a specific influence over space-time if they weren't able to control the particle or field at will? How...

The supposed discovery of the Higgs three years ago was widely celebrated. Nobel prizes were handed out and the mystery of the origin of mass is now explained. But does the Higgs actually explain mass at all? When thinking about the Higgs, I think it's best to ask these questions first: 1...

I watched a Stephen Hawking series a few months after reading an article about the significance of the Higgs Field and throughout the entire Stephen Hawking thing I was plagued by the notion that some aspects of relativity, such as how as something speed up as it gains mass could be explained...

http://arxiv.org/abs/1507.05760 Higgs boson cosmology Ian G. Moss (Submitted on 21 Jul 2015) The discovery of the Standard Model Higgs boson opens up a range of speculative cosmological scenarios, from the formation of structure in the early universe immediately after the big bang, to relics...

Homework Statement Hi, I study the Higss sector of the MSSM from this review " arxiv:0503173v2", "The Higgs bosons in the Minimal Supersymmetric Model", In Sec.: 1.2, it gives the Higgs potential by Equ. (1.60), then after acquiring the vevs and minimizing the potential to get the masses...

[Moderator's note: Thread moved to Quantum Physics since it is more appropriate there.] O.K., I'm confused: According to How Stuff Works http://science.howstuffworks.com/higgs-boson1.htm "Can't matter just inherently have mass without the Higgs boson confusing things? Not according to the...

http://arxiv.org/pdf/hep-ph/0410370v2.pdf 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?

Higgs bosson as we know is responsible to giving particles mass, mass is responsible for the gravity. So I think higgs bosson can be used to manipulated gravity. If we can made the device that can manipulate gravity using higgs bosson, can we make 4 dimensional space? can we make the real...

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?

I'm new to quantum physics, and this might be a stupid question. What is the difference between Photons and the Higgs Boson? I know that neither of them interact with the Higgs field. And that when CERN found the Higgs Boson, it decayed into other particles INCLUDING photons. So what's the...

Hi all, In A. Djouadi's review for Higgs, volume II, " arXiv:hep-ph/0503173v2 ", Sec. 1.2.3, it discuss the couplings of SUSY new scalars with gauge bosons, there are some points I don't understand: - CP–invariance forbids WWA, ZZA and W ZH ± couplings - For the couplings between two Higgs...

How would someone measure the Higgs spin? I have a feeling that the spin would somehow affect the symmetry of the decays...? A spin zero would have to show a spherically symmetric distribution of decay products (independent on ##\theta##, maybe a little dependent on ##\eta## due to the...

Do you believe the Higgs boson was already experimentally confirmed? I guess that, as with any elementary particle, the Higgs boson should have a lot of theoretical properties that must all be experimentally confirmed to be sure it is Higgs' and not some other entity. Have the scientists...

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...

Is it possible to have a free massless scalar field in 1+1 spacetime and then add another field of the right type which interacts with some adjustable strength with the massless field to give mass to the massless field? Is there a Higgs-like mechanism in 1+1 spacetime? Thanks for any help!

Problem I have a project for my university class on the Higgs fields and how it impacts the standard model, and how the Higgs particle is formed and decays into particles with the probability of decay based on the mass of the particles it will decay into. I need resources that I can cite like...

So, the Higgs boson might be one of the most important discoveries in terms of the standard model. I'm new to the standard model, and had a few questions related to the future of its research. If the Higgs is ultimately what creates gravitational fields, or at least gives things mass (and is...

Hi, so my question is along the lines of the following: If I'm looking at the decay channel H=>ZZ=>4 Muons, why would the resultant distribution for the mass of the parent Higgs be a Gaussian? Is it a case of the peak is the actual value of the Higgs at rest; those of greater mass are Higgs...

I am confused about how the gauge boson W+ and W- get their charge under spontaneous symmetry breaking in the Higgs mechanism. Here's what I have so far: The covariant derivative for a SU(2)⊗U(1) is DμΦ = (∂μ + igWμiσi/2 + ig'Bμ)Φ where g and g' are coupling constants. SU(2) is associated...

What are the lines of investigation right now? I'd have listened that it could be more than one kind of Higgs particle, which ones? What if them are found? Could an arbitrary universe exist without the Higgs field? or it would exist as a it must exist? (maybe this is very philosofical) What...

from a malayalam language newspaper i read about Higgsboson that is according to standard model the Higgsboson is the piece of the atom that endows all the other piece with their mass. when electrons,quarks,etc are associated with higgs field they get mass. the light particle called photons have...

Some popular explanations of the Higgs boson go something like this: 'Without the Higgs, all the energy bits we call fundamental particles would be moving at the speed of light and could not interact with each other, nothing would 'happen'. The interaction with the Higgs field give those...

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...

When you accelerate higgs.. would it travel the same as photon with alternating magnetic and electric field traveling on permissitity and permeability of the vacuum. In other words, how do you make scalar particles travel? If we can make really sensitive Higgs detector.. then you make higgs...

http://www.huffingtonpost.com/2015/03/03/homer-simpson-higgs-boson_n_6793204.html?utm_hp_ref=media&ir=Media According to Simon Singh, in a 1998 episode the writers of the Simpsons had Homer in front of blackboard with a supposedly accurate calculation of the mass of the Higgs boson. Hmm...

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?

What is the electric charge of Higgs particle?Then if it is charge particle why must we give that particle the charge? In GWS model we introduce a scalar field in the spinor representation of SU(2):(H^+,H^0) .Then why must we choose positive charge for H^+? Now,I think that Q=T^3+Y/2,and we...

When we discuss higgs potential energy in textbook, we mean it takes the form ## V(h)= m^2 h^2 + \lambda h^4/4##. My question is: is potential energy always defined at some specific energy scale? since the parameters depend on energy. For instance, if I am interested in the form of higgs...

I am concerned about the idea of decay of HB... when two photons collide in Hadron .. exploding outward.. as the proton remnants leave trails in the field surrounding .. revealing a smaller particle field which quickly disappear... My contemplations lead me to think they do NOT quickly decay...

I was reading a book that said the Higgs Boson destroys itself within trillionth of a second, I really did not understand this, so what does it mean?

Hi all, I have some points not so clear for me about the fermions mass terms in SM; first, why ## \bar{\psi}\psi = \bar{\psi}_L \psi_R + \bar{\psi}_R \psi_L ##, that since ## \bar{\psi} = \bar{\psi}_R + \bar{\psi}_L ## and ## \psi = \psi_R + \psi_L ## Where are such terms: ## \bar{\psi}_R...

Every gauge boson is within a field and carries a force. Higgs is a scalar (spin 0) boson. I am not sure which category a graviton (spin 2) would fit into, but it surely would carry a force. Is it possible that Higgs carries a force that we have not recognized yet?

Hi all, I read one of the CMS results for new charged Higgs on : https://twiki.cern.ch/twiki/bin/view/CMSPublic/Hig14020TWiki I can't understand this sentence at the main results: What does it mean? is that constrains the theoretical calculations of sigma(pp -> H+- tb) to be 0.41-0.030 pb...

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...

Hi, I wonder if a theory like 2HDM has a new triple Higgs coupling, like ##g_{hH^+H^-}##, what governs how much is this coupling ? For example a paper as : arXiv:1405.3584v1 [hep-ph], they normalize ##g_{hH^+H^-}## by the SM ##g_{hWW}##, they plotted at fig. 3 (f)...

Now we are presumably creating (?) Higgs Bosons in the collider. But the universe is permeated already by the Higgs field and Higgs bosons. When the colliders make an "artificial" Higgs, what conservation laws (in addition to energy, momentum, charge, isospin, baryon number etc.)are obeyed? In...

Homework Statement A Higgs boson has mass 125 GeV/c2, decaying into a pair of Z bosons, mass 91 GeV/c2. In the lab frame, one of the Z bosons is at rest. Determine the kinetic energy for the other Z boson in this laboratory frame. Homework Equations E = γmc2 γ=1/√(1-β2) The Attempt at a...

I am looking for the famous CMS and ATLAS papers which announced the discovery of a new boson particle... Could someone help me by posting the link here?

I understand that Higgs mechanism “gives” mass to particles in QM sense. My first question is, why it also gives mass in GR sense, bending space-time? Of course, I don’t expect an answer now as it is definitely a TOE/Quantum gravity territory. However, let me rephrase my question in a narrower...

If the Higgs boson is an excitation in the Higgs field, does that mean that it is exceedingly rare? Do they exist only on earth, or are they also created in high energy places such as quasars? Are the number of Higgs bosons that have existed in the universe on the order of hundreds, billions, or...

Do gauge fields work the same way as the Higgs field? Are gauge fields all encompassing too, like the Higgs field? What are the differences between the functioning of gauge fields and Higgs field?

Hello. I am an amateur. Is a Higgs boson to the Higgs field the same as an Electron(oops boson)to the electric field? Thx SC

Hi all, I wonder if I study new Higgs scalars, How the data of the LHC for searching for heavier scalars in h-> WW->lvlv and h -> ZZ-> 4 l channels like in [arXiv:1304.0213] can make constrain on my study for the new Higgs? How a figure like figure 2 can give constrains on my model free...
