Massive three-loop form factors: anomaly contribution
Matteo Fael, Fabian Lange, Kay Schönwald +1
We compute three-loop corrections to the singlet form factors for massive quarks using a semi-analytic method which provides precise results over the whole kinematic range. Particu…
Massive form factors at
Kay Schönwald
We report on our recent calculation of massive quark form factors using a semi-numerical approach based on series expansions of the master integrals around singular and regular kin…
Higgs boson contribution to the leading two-loop Yukawa corrections to
Joshua Davies, Go Mishima, Kay Schönwald +2
We analytically compute two-loop Yukawa corrections to Higgs boson pair production in the high-energy limit. Such corrections are generated by an exchange of a Higgs boson between…
Singlet and non-singlet three-loop massive form factors
Matteo Fael, Fabian Lange, Kay Schönwald +1
We consider Quantum Chromodynamics with external vector, axial-vector, scalar and pseudo-scalar currents and compute three-loop corrections to the corresponding vertex function tak…
Leptoquark Flavor Patterns & B Decay Anomalies
Gudrun Hiller, Dennis Loose, Kay Schönwald
Flavor symmetries that explain masses and mixings of the standard model fermions dictate flavor patterns for the couplings of scalar and vector leptoquarks to the standard model fe…
