Questions tagged [particle-physics]
Particle physics is the study of the fundamental forces of nature as they are embodied in the interactions of elementary and composite particles at high energies and short time and distance scales. DO NOT USE THIS TAG for point particles in classical mechanics.

Does Matters Persist in Some Form Forever?
If all particles/matters eventually decay or annihilate in the distant future, will all the matter they once composed persist in some form forever, even after the universe reaches its (all scenerios ...

Why would I trust the data publish by the particle-physics community? [closed]
In my opinion, the generation of data is so complicated that no external party can check them. If that is true, why would I trust the published data, if they are only checked by parties within the ...

Permanence of the basic forces
I am a highly interested layperson in Germany focusing on the fundamental principles that govern our everyday reality.
I have a specific question regarding the permanence of the basic forces of ...

Where do the charge and mass go when a gluon pops out of existence? [duplicate]
A nucleon is made up of a sea of quarks and gluons that pop in and out of existence. Color charged gluons move at $c$ and thus make up 99% of the mass of the atom. Where does this charge and kinetic ...

Is it possible to generate electricity from muons instead of photons?
I understand that solar panels generate electricity by converting photons from sunlight. This made me wonder whether it would be possible to use other types of cosmic radiation, such as muons, to ...

Does Spacetime Curvature affect the Higgs Trilinear Self-Coupling by modifying the Vacuum Expectation Value?
I have been studying the Higgs mechanism, and most standard derivations assume flat Minkowski spacetime.However, in the early universe or near compact objects such as black holes, spacetime curvature ...

Why a particle (specifically lepton) decays?
This is a sequel of my question. For particles with structure, it wouldn’t be strange for them to decay due to unstable structure and various reasons. But for leptons, such as the muon, it's almost ...

Positive values of Mandelstam variable $t$
Is it possible for the Mandelstam variable $t$ to reach positive values in the quasielastic charged current neutrino-neutron scattering?:
$$\nu_{\mu} + n \rightarrow \mu^- + p$$
(don't assume that ...

How can Different neutrino flavours have different masses?
I've heard about neutrino oscillation, where can neutrino can change between each flavour. I've also heard that the neutrino flavours are not guaranteed to have the same mass. If this is the case how ...

Will a Higgs factory reveal something new besides testing existing theories?
After the discovery of Higgs boson at LHC, multiple lepton colliders like FCC-ee, ILC, CLIC, and muon colliders were proposed. These colliders can produce Higgs bosons under very clean backgrounds to ...

Energy-dependent width of a Breit-Wigner for $\ell=0$?
I am doing calculations with a resonance with the invariant mass $W$, which can decay to $a + b$ with masses $m_a$ and $m_b$. Since I treat all particles as scalar, I calculate with $\ell=0$. The ...
