质子衰变中的核效应

Nuclear effects in proton decay

Dorota Stefan, Artur M. Ankowski

摘要:

对质子衰变的实验观测将是大统一的有力证明。目前,来自超级神冈实验的p->e+ pi 0衰变通道的质子寿命的最佳约束达到8*10^33年。为了改善测量,应该建造更大的探测器。此外,还必须对束缚核子态和质子衰变产物通过核物质的传播进行更好的描述。在这篇文章中,特别注意的是氩核,因为液态氩探测器是一个有前途的候选人,为未来的大型装置。

英文摘要:

An experimental observation of proton decay would be a spectacular proof of grand unification. Currently, the best constraint on the proton lifetime for the p->e+ pi0 decay channel, coming from the Super-Kamiokande experiment, reaches 8*10^33 years. To improve the measurement, much bigger detectors should be constructed. Moreover, a better 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.
