Two-loop correction to the decay BD π — •Susanne Kränkl and Tobias Huber — Universität Siegen

The rich amount of B decays yield a broad spectrum of observables for investigating the flavour structure of the Standard Model. The theory description of various of these observables is based on QCD factorization, a model independent framework that exploits the structure of a decay amplitude in the heavy-mass limit. Two-loop corrections to certain non-leptonic B decay provide a further test of this framework.
In this talk we present the result for the hard scattering kernel to the decay B0D+ π to two-loop accuracy. The calculation was performed by applying commonly used multi-loop techniques like Laporta’s reduction to master integrals and Mellin Barnes representations and differential equations for evaluating the latter.
