NUCLEAR EFFECTS IN PROTON DECAY∗

Dorota Stefan
Artur M. Ankowski

Publication date

January 2008

Abstract

An experimental observation of proton decay would be a spectacu-lar proof of Grand Unification. Currently, the best constraint on the proton lifetime for the p → e+pi0 decay channel, coming from the Su-perKamiokande experiment, reaches 8 × 1033 years. To improve the mea-surement, much bigger detectors should be constructed. Moreover, a bet-ter description of the bound-nucleon states and of the propagation of the proton-decay products through nuclear matter have to be developed. In this article special attention is paid to the argon nucleus because a liquid argon detector is a promising candidate for the future large apparatus. PACS numbers: 13.30.Ce, 14.20.Dh, 24.10.Lx, 27.40.+z 1
