The influence of dimension eight operators on weak matrix elements
Mu dimension calculation matrix elements scale dimensional regularization
2014/12/22
I describe recent work with V. Cirigliano and E. Golowich on the effect of dimension eight operators on weak nonleptonic amplitudes. The basic mesage is that there is an inconsistency in the way that ...
