Universal Two-Loop Current--Current Renormalization of Four-Fermion Operators
Jason Aebischer, Sudeepan Datta, Pol Morell +2
The complete one- and two-loop gauge and scalar current--current contributions to the running of arbitrary dimension-six four-fermion operators are reported. The results are obtain…

Inclusive Charmless Non-Leptonic B Decays at NLO within and beyond the Standard Model
Stefan Meiser, Pol Morell, Angel Picazo +1
We calculate the full set of BSM contributions to the inclusive non-leptonic -meson lifetime from charmless final states within the framework of the Weak Effective Theory up to…

Two-Loop Anomalous Dimensions in the LEFT: Dimension-Six Four-Fermion Operators in NDR
Jason Aebischer, Pol Morell, Marko Pesut +1
We derive the complete set of two-loop anomalous dimensions describing the mixing of four-fermion operators in the Low Energy Effective Field Theory (LEFT). The calculation is perf…
