NNLO QCD corrections to the weak radiative $B$ -meson decay with exact dependence on $m_{c}$

M. Czaja, M. Czakon, T. Huber +5

The inclusive weak radiative $B$ -meson decay provides important constraints on many popular extensions of the Standard Model. Some of the numerically relevant Next-to-Next-to-Leadi…

The inclusive $B ˉ \to X_{s} γ$ decay rate with higher precision

M. Misiak, H. M. Asatrian, K. Brune +11

We present a new and upgraded analysis of the inclusive weak radiative decay of the $B$ meson in the standard model and beyond. The $O (α_{s})$ perturbative corrections are…

Revisiting semileptonic $B$ 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 $B$ mesons for arbitrary values of the final-state quark mass. For the contribution with one…

Next-to-leading order electroweak corrections to $g g \to H H$ and $g g \to g H$ in the large- $m_{t}$ limit

Joshua Davies, Kay Schönwald, Matthias Steinhauser +1

We compute two-loop electroweak corrections to Higgs boson pair and Higgs plus jet production, taking into account all sectors of the Standard Model. All diagrams with virtual top…

Towards $g g \to H H$ at next-to-next-to-leading order: light-fermionic three-loop corrections

Joshua Davies, Kay Schönwald, Matthias Steinhauser

We consider light-fermion three-loop corrections to $g g \to H H$ using forward scattering kinematics in the limit of a vanishing Higgs boson mass, which covers a large part of the ph…

Analytic approximations of $2 \to 2$ processes with massive internal particles

Joshua Davies, Go Mishima, Kay Schönwald +1

We consider two-loop corrections to $2 \to 2$ scattering processes with massive particles in the final state and massive particles in the loop. We discuss the combination of analyti…
