Nonleptonic -meson decays to next-to-next-to-leading order
Manuel Egner, Matteo Fael, Kay Schönwald +1
We compute next-to-next-to-leading order QCD corrections to the partonic processes and , which constitute the dominant decay channels in standa…
Heavy-to-light form factors to three loops
Matteo Fael, Tobias Huber, Fabian Lange +3
We compute three-loop corrections of to form factors with one massive and one massless quark coupling to an external vector, axialvector, scalar, pseudoscala…
Analytic results for massive processes
Matthias Steinhauser
We discuss recent (semi) analytic results for processes with massive internal and external particles in various regions of phase space. In the physical applications we res…
Three-loop vertex with current-current operators
Matteo Fael, Fabian Lange, Kay Schoenwald +1
We compute three-loop vertex corrections to induced by current-current operators. The results are presented as expansions in with numerical coefficients which a…
On charm-mass dependent NNLO corrections to B -> Xs gamma
M. Misiak, A. Rehman, M. Steinhauser
The inclusive radiative decay of the B meson is known to provide strong constraints on many popular extensions of the Standard Model. Such constraints crucially depend on precision…
Hyperfine splitting in positronium to : one-photon annihilation contribution
Marc Baker, Peter Marquard, Alexander Penin +2
We present the complete result for the one-photon annihilation contribution to the hyperfine splitting of the ground state energy levels in positronium. Numerica…
