In particle physics, proton decay is a hypothetical form of particle decay in which the proton decays into lighter subatomic particles, such as a neutral pion and a positron. [1] The proton decay hypothesis was first formulated by Andrei Sakharov in 1967. Despite significant experimental effort, proton decay has never been observed.
IMB detected fast-moving particles such as those produced by proton decay or neutrino interactions by picking up the Cherenkov radiation generated when such a particle moves faster than light's speed in water. Since directional information was available from the phototubes, IMB was able to estimate the initial direction of neutrinos.
The Harari–Shupe preon model (also known as rishon model, RM) is the earliest effort to develop a preon model to explain the phenomena appearing in the Standard Model (SM) of particle physics. [1]

In particle physics, particle decay is the spontaneous process of one unstable subatomic particle transforming into multiple other particles. The particles created in this process (the final state ) must each be less massive than the original, although the total mass of the system must be conserved.
Beta decay transforms a neutron into proton or vice versa. When a neutron inside a parent nuclide decays to a proton, an electron, a anti-neutrino, and nuclide with high atomic number results. When a proton in a parent nuclide transforms to a neutron, a positron, a neutrino, and nuclide with a lower atomic number results. These changes are a ...
In addition to Standard Model particles, the theory includes 30 colored X bosons, responsible for proton decay, and two W' bosons. The pattern of charges for particles in the SO(10) model, rotated to show the embedding in E6. In particle physics, SO(10) refers to a grand unified theory (GUT) based on the spin group Spin(10).
Proton emission (also known as proton radioactivity) is a rare type of radioactive decay in which a proton is ejected from a nucleus.Proton emission can occur from high-lying excited states in a nucleus following a beta decay, in which case the process is known as beta-delayed proton emission, or can occur from the ground state (or a low-lying isomer) of very proton-rich nuclei, in which case ...
