Fundamental particles Definition and 26 Threads

Basically, I've become more interested in particle physics and accelerators, but I was just wondering what kind of experiments could be done with one if you had one. I've seen the general experiments and the ones that have already been done but I'm looking for new and unique ideas. No particular...

We know that the energy levels for electrons surrounding nucleus are quantized , only coming in discrete levels. When I see the standard model of elementary particles table I notice specific masses for each of the particles whether they be quarks or leptons or bosons like the higgs. I know that...

I am trying to code a simulator for fundamental particles. The problem is that on a subatomic level, force works differently than on a macroscopic level. Then there is also the problem of Heisenberg's Uncertainty Principle. How is a force applied to a subatomic particle? I did some research and...

Mesons and baryons have both a ground state and excited states involving the same valence quarks but a higher mass (which can in principle be calculated from QCD). Fundamental fermions and bosons, however, do not appear to display this behavior. They have a ground state, and while there are...

Hi, we know that the particles have intrinsic properties for them electric field and magnetic moment, but for what I mean particles, I mean quarks, the fundamental blocks of (protons, neutrons and mesons) with everything that nobody explained as electric and The magnetic field of a particle and...

I remember reading in some book, that the most important experiments are those that produce negative results: the Michelson-Morley experiment for example. The standard model is complete after the Higgs boson. I believe that if no new particle appears in CERN, it would be one of the greatest...

I am aware that according to the Standard Model of Particle Physics, fundamental particles such as electrons and quarks are treated as point-like particles. However, if fundamental particles are indeed 0-dimentional points with no spatial extent, it creates problems (i.e. fundamental particles...

Is it possible that fundamental point like particles (ie electrons) are actually particles with shape size and structure that are too small for any of our current technology to detect?

why is each fundamental particle round

Are quarks really considered fundamental particles that cannot be divided further? If an up quark can transmute to a down quark and release a W+ boson which decays to a positron and a neutrino (for example) - doesn't this mean that there is substructure to a quark? What exactly is it that makes...

If electrons are fundamental particles and leptons then what happens when they emit or absorb photons or Z particles? What is known about the mechanism of these aborptions or emissions for any particles? Do the absorbed electrons gain mass as particles are described to do as they move nearer to...

Heat is a product of excited energy states of the fundamental particles that make up atoms, correct? So do the particles, themselves, get "hot" - or is heat just experienced as radiation on the macroscopic scale? Do neutrons, for example, have a thermal property at all?

1. What (property) makes a photon less likely to decohere/(entangle with the environment) relative to other "fundamental" particles (non leptons?) such as an electron?...say during single particle interference experiment Photon single particle interference can done without the need for a...

I was reading this recent Scientific american article which I found interesting, and was spurred on by it to ask a couple of questions. Is the mathematical concept of fundamental point particle currently a basic postulate in physics(let's take as current physics the QM based-QFT modern...

Graphic Design & Science: Fundamental Particles Visualisation Hello my name is Brendon. I'm a graphic designer interested in science communication and currently studying a masters in graphic design. I was wondering if anybody would be able to help me with a few queries with regards to...

Homework Statement The pion-zero meson has its mass quoted as 135.0MeV/c2. It decays into two gamma rays: ∏0 → γ + γ b) Assuming the ∏0meson to be initially at rest, calculate the energy and hence the wavelength of the two gamma rays. Homework Equations E= hc/λ The Attempt at a...

True or false? 1. It is not possible to prove the point of origin of a photon 2. It is not possible to prove the point of origin of a free electron 3. It is not possible to prove that protons or neutrons exist inside a nucleus Can someone please confirm?

If one were to subtract the kinetic energies of all fundamental particles within hydrogen, as well as all of the potential energy of all bound states between these particles, how much mass (as a percentage of the total) would remain? Ignore the kinetic energy due to the hydrogen's speed.And...

I'm confused, by composite particle we probably mean when we use something to smash it, something new will come up, right? Then what's so different about fundamental particles? For example if we "smash" a electron with a positron, we also get something new--photon. I guess I am making some...

How were the masses of fundamental particles(electrons,protons,neutrons) determined?

Problems with fundamental particles and quarks :( Hi, I have no idea where to post this so I hope its ok... I'm studying A level physics. We have a topic on fundamental particles. Yea couple of questions... 1. Whats the difference between a (insert lepton here)-neutrino, and its...

I attended a colloquium a few days ago concerning the LHC and the search for the Higgs Boson. After some thought, I have the following question. Among other things, there are two measurable properties of all of the fundamental particles in the Standard Model: mass and charge. It is...

Is there a fundamental particle (like a Planck black hole) that has a finite radius?

Which are (basic?) quantum nubers of fundamental particles? I am having problems becouse a lot of expresions are used on sites on the web: el. charge, color charge, mass, taste, spin, barion & lepton number... to many :eek: :confused:

Perhaps this question has been addressed before, but, allow me to ask: What consitutes the classification of a "fundamental" particle? Does a fundamental particle have ANY half-life? Seems it would not. Is a fundamental particle completely impervious to destruction?

Does anyone know of any good references on the relationship between string vibrations and fundamental particles such as quarks, leptons, and the gauge bosons, containing an explicit mathematical description of said relationship? Any information would be appreciated.
