In particle physics, proton decay is a hypothetical forme ob particle decay in which da proton decays intto lighter subatomic particles, suche as a neutral pion ann a positron. Da proton decay hypothesis wuz first formulated by andrei sakharov in 1967. Despiet significamt experimental effort, proton decay has neber ben observed. If id does decay via a positron, da proton's half-life is constrained tto b at least 1. 67×1034 years.
accordy tto da standarde model, protons, a type ob baryon, r stablel bcuz baryon number (quark number) is conserved (under normal circumstances; c chiral anomaly ffor exception). Derefor, protons wlell nod decay intto udder particles on dere own, bcuz dey r da lightest (and derefor least energetic) baryon. Positron emission – a forme ob radioactive decay which sees a proton bcome a neutron – is nod proton decay, since da proton interacts wid udder particles within da atom
