Perturbative corrections to B to X_s gamma in supersymmetry at next-to-leading order
Christoph Greub, Tobias Hurth, Volker Pilipp +1
We give a brief overview about perturbative corrections to the inclusive decay mode B to X_s gamma in supersymmetric models.
Complete next-to-leading order gluino contributions to b--> s gamma and b--> s g
Christoph Greub, Tobias Hurth, Volker Pilipp +2
We present the first complete order alpha_s corrections to the Wilson coefficients (at the high scale) of the various versions of magnetic and chromomagnetic operators which are in…
b --> s\ell^+\ell^- in the high q^2 region at two-loops
Volker Pilipp, Christof Schupbach
We report on the first analytic NNLL calculation for the matrix elements of the operators O_1 and O_2 for the inlusive process b --> X_s l^+l^- in the kinematical region q^2>4m_c^2…
B- -> pi- pi0/rho- rho0 to NNLO in QCD factorization
Guido Bell, Volker Pilipp
The approximate tree decays B- -> pi- pi0/rho- rho0 may serve as benchmark channels for testing the various theoretical descriptions of the strong interaction dynamics in hadronic…
Analytic calculation of two-loop QCD corrections to b\to s\ell^+\ell^- in the high q^2 region
Christoph Greub, Volker Pilipp, Christof Schüpbach
We present our results for the NNLL virtual corrections to the matrix elements of the operators O_1 and O_2 for the inclusive process b\to s\ell^+\ell^- in the kinematical region q…
Semi-numerical power expansion of Feynman integrals
Volker Pilipp
I present an algorithm based on sector decomposition and Mellin-Barnes techniques to power expand Feynman integrals. The coefficients of this expansion are given in terms of finite…
