摘要
We study the resonantly enhanced C P-asymmetry in the decays of nearly mass-degenerate heavy right-handed Majorana neutrinos for which different formulae have been presented in the literature, depending on the method used to calculate it. We consider two different techniques and show that they lead to the same result, thereby reconciling the different approaches. (c) 2006 Elsevier B.V. All rights reserved.
