Recent developments in radiative B decays
T. Huber
We report on recent theoretical progress in radiative B decays. We focus on a calculation of logarithmically enhanced QED corrections to the branching ratio and forward-backward as…
Logarithmically Enhanced Corrections to the Decay Rate and Forward Backward Asymmetry in anti-B --> X(s) l+ l-
Tobias Huber, Tobias Hurth, Enrico Lunghi
We study logarithmically enhanced electromagnetic corrections to the decay rate in the high dilepton invariant mass region as well as corrections to the forward backward asymmetry…
Master Integrals for Fermionic Contributions to Massless Three-Loop Form Factors
G. Heinrich, T. Huber, D. Maitre
In this letter we continue the calculation of master integrals for massless three-loop form factors by giving analytical results for those integrals which are relevant for the ferm…
HypExp 2, Expanding Hypergeometric Functions about Half-Integer Parameters
T. Huber, D. Maître
In this article, we describe a new algorithm for the expansion of hypergeometric functions about half-integer parameters. The implementation of this algorithm for certain classes o…
On one master integral for three-loop on-shell HQET propagator diagrams with mass
A. G. Grozin, T. Huber, D. Maitre
An exact expression for the master integral I_2 arising in three-loop on-shell HQET propagator diagrams with mass is derived and its analytical expansion in the dimensional regular…
