epsilon'/epsilon at the NLO: 10 Years Later
epsilon'/epsilon at the NLO: 10 Years Later
During the last four years several parameters relevant for the analysis of the CP-violating ratio epsilon'/epsilon improved and/or changed significantly. In particular, the experimental value of epsilon'/epsilon and the strange quark mass decreased, the uncertainty in the CKM factor has been reduced, and for a value of the hadronic matrix …
