Matching the Standard Model to HQET and NRQCD
- 1. Hamburg University (Germany). II. Institute für Theoretische Physik
Description
We find the leading electro-weak corrections to the HQET/NRQCD Lagrangian. These corrections appear in the Wilson coefficients of the two and four quark operators and are considered here up to O(1/m) at one-loop order. The two quark operators up to this order will include new CP-violating terms, which we derived analogously to the CP preserving QCD result at one-loop order.
