Total decay rates of mesons at NNLO-QCD

Manuel Egner, Matteo Fael, Alexander Lenz +4

We update the Standard Model (SM) predictions for the lifetimes of the , and mesons within the heavy quark expansion (HQE), including the recently determined NNLO-…

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…

Nonleptonic B-decays at NNLO

Manuel Egner

The decay of B mesons can be predicted within the Heavy Quark Expansion as the decay of a free bottom quark plus corrections which are suppressed by powers of . This contrib…

Revisiting semileptonic meson decays at next-to-next-to-leading order

Manuel Egner, Matteo Fael, Kay Schönwald +1

We compute next-to-next-to-leading order corrections to the semileptonic decay rate of mesons for arbitrary values of the final-state quark mass. For the contribution with one…

Three-loop non-singlet matching coefficients for heavy quark currents

Manuel Egner, Matteo Fael, Fabian Lange +2

We compute the matching coefficients between QCD and non-relativistic QCD for external vector, axial-vector, scalar and pseudo-scalar currents up to three-loop order. We concentrat…

Charm-quark mass effects in NRQCD matching coefficients and the leptonic decay of the meson

Manuel Egner, Matteo Fael, Jan Piclum +2

We compute two-loop corrections to the vector current matching coefficient involving two heavy quark masses. The result is applied to the computation of the decay width int…
