Two-loop mixing of dimension-five flavor-changing operators

High Energy Physics - Phenomenology 2011-07-19 v3

Abstract

We calculate the two-loop QCD mixing of the dimension-five flavor-changing operators that arise in the Standard Model after integrating out the WW, ZZ and Higgs bosons and the top-quark, i.e.~the mixing among gluonic and photonic magnetic moment operators. Our calculation completes the two-loop anomalous dimension matrix of operators that govern low energy flavor-changing processes. It is an important ingredient of the next-to-leading calculation of the BXsγB \rightarrow X_s \gamma decay rate.
