Does proton decay follow the exponential law?

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

In this paper, we discuss the exponential law for proton decay. By using a simple model based uponSU(5)GUT and the current theories of hadron structure, we explicitly show that the corrections to the Wigner-Weisskopf approximation are quite negligible for present day protons, so that their eventual decay should follow the exponential law. Previous works are critically analyzed.
