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…

Three loop QCD corrections to the heavy-light form factors: fermionic contributions
Sudeepan Datta, Narayan Rana
We present analytic results for three-loop fermionic corrections to the heavy-light form factors in perturbative quantum chromodynamics. Specifically, we present all light quark co…

Three loop QCD corrections to the heavy-light form factors in the color-planar limit
Sudeepan Datta, Narayan Rana, V. Ravindran +1
We present the analytic expressions for the color-planar contributions to the heavy-light form factors at three loops in perturbative QCD. These form factors play an important role…
