The unpolarized twoloop massive pure singlet Wilson coefficients for deepinelastic scattering
/ Blümlein, J. ; De Freitas, A. ; Raab, C.G. ; Schönwald, K.
We calculate the massive two–loop pure singlet Wilson coefficients for heavy quark production in the unpolarized case analytically in the whole kinematic region and derive the threshold and asymptotic expansions. [...]

The O ( α 2 ) initial state QED corrections to e + e − annihilation to a neutral vector boson revisited
/ Blümlein, J. ; De Freitas, A. ; Raab, C.G. ; Schönwald, K.
We calculate the nonsinglet, the pure singlet contribution, and their interference term, at O(α2) due to electronpair initial state radiation to e+e− annihilation into a neutral vector boson in a direct analytic computation without any approximation. [...]

The variable flavor number scheme at nexttoleading order
/ Blümlein, J. ; De Freitas, A. ; Schneider, C. ; Schönwald, K.
We present the matching relations of the variable flavor number scheme at nexttoleading order, which are of importance to define heavy quark partonic distributions for the use at high energy colliders such as Tevatron and the LHC. [...]

The twomass contribution to the threeloop gluonic operator matrix element Agg,Q(3)
/ Ablinger, J. ; Blümlein, J. ; De Freitas, A. ; Goedicke, A. ; et al
We calculate the twomass QCD contributions to the massive operator matrix element Agg,Q at O(αs3) in analytic form in Mellin N  and z space, maintaining the complete dependence on the heavy quark mass ratio. [...]

Double hard scattering without double counting
/ Diehl, Markus ; Gaunt, Jonathan ; Schönwald, Kay
Double parton scattering in protonproton collisions includes kinematic regions in which two partons inside a proton originate from the perturbative splitting of a single parton. [...]

Leptoquark flavor patterns & B decay anomalies
/ Hiller, Gudrun ; Loose, Dennis ; Schönwald, Kay
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 fermions. [...]
