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…
FeynGKZ: a Mathematica package for solving Feynman integrals using GKZ hypergeometric systems
B. Ananthanarayan, Sumit Banik, Souvik Bera +1
In the Lee-Pomeransky representation, Feynman integrals can be identified as a subset of Euler-Mellin integrals, which are known to satisfy Gel'fand-Kapranov-Zelevinsky (GKZ) syste…
Quadratic and quartic integrals using the method of brackets
B Ananthanarayan, Sumit Banik, Sudeepan Datta +1
We use the method of brackets to evaluate quadratic and quartic type integrals. We recall the operational rules of the method and give examples to illustrate its working. The metho…
