Why does everyone assume that particles decay is an ergodic random process? After all T is not a symmetry of the Standard Model and I don't see any reason why ensamble averages should be equal to time averages.
Not in places where it would matter.Carlos L. Janer said:you physicists ASSUME that this stochastic process is ergodic
Proton decay is a hypothetical process in which a proton, one of the building blocks of atoms, decays into lighter particles. It is not yet observed, but if it exists, it would violate the conservation of baryon number and fundamentally change our understanding of particle physics.
If proton decay is confirmed, it would have significant implications for our understanding of the structure and stability of matter. It could also provide clues about the unification of the fundamental forces of nature and the origin of the universe.
Ergodicity is a mathematical concept that describes how a system evolves over time. Proton decay is often studied in the context of ergodicity to understand the probability of a proton decaying and how it may change over time.
According to the standard model of particle physics, proton decay is possible but extremely rare. However, it has not been observed yet, and some theories beyond the standard model predict a longer proton lifetime or no proton decay at all.
Scientists use large detectors, such as the Super-Kamiokande and the Deep Underground Neutrino Experiment, to search for evidence of proton decay. They look for specific decay signatures, such as the emission of gamma rays or other particles, that would indicate a proton decay event.
