Proton decay is a hypothetical form of radioactive decay in which the proton decays into lighter subatomic particles. There is currently no experimental evidence that proton decay.

Proton decay is a hypothetical form of radioactive decay in which the proton decays into lighter subatomic particles. There is currently no experimental evidence that proton decay. Experimental physicists search for proton decay as it is one of the few observable effects of the various proposed GUTs models. See the PDG entry for protons and this wikipedia page for more details.

Proton Decay Modes

May I know the proton decay mode predicted by Theoretical Physics? These are the decay mode I've found: 1: $p^+\rightarrow e^++\pi^0$ 2: $p^+\rightarrow \mu^++\pi^0$

Proton decay - Kamiokande experiment

The Kamiokande experiments measure proton decay using water, i.e. probing the proton in an H-atom. The electron in the H-atom has a nonzero probability at the proton position. It is well known that the environment influences decay (neutron),…

What is the maximum proton lifetime allowed by the standard model?

Is some amount proton decay necessary in the standard model or is it possible for the proton lifetime to be infinite?

The half-life of carbon-12

Let us denote the half-life of the proton by $Y_p$. (There is, of course, no experimental evidence that $Y_p<\infty$, but there are theories that assert it, so this is really a question about those theories). The question is: what, in that case, is…

are protons in proton decay allowing theories stable inside nuclei?

It is known that isolated neutrons are unstable, but that neutrons inside nuclei can be stable. I know there are candidate theories that allow proton decay but I wonder whether in these theories protons might be stable inside nuclei. Is it so?
