Two-loop QCD penguin contribution to the width difference in $B_{s} - B ˉ_{s}$ mixing

Marvin Gerlach, Ulrich Nierste, Vladyslav Shtabovenko +1

We consider two-loop QCD corrections to the element $Γ_{12}^{q}$ of the decay matrix in $B_{q} - B ˉ_{q}$ mixing, $q = d, s$ , in the leading power of the Heavy Quark Expansion. The calcul…

Matching coefficients in NRQCD to two-loop accuracy

Marvin Gerlach, Go Mishima, Matthias Steinhauser

We consider the Lagrange density of non-relativistic Quantum Chromodynamics expanded up to order $1/ m^{2}$ , where $m$ is the heavy quark mass, and compute several matching coefficien…

Wilson coefficients for Higgs boson production and decoupling relations to $O (α_{s}^{4})$

Marvin Gerlach, Florian Herren, Matthias Steinhauser

An important ingredient for the calculation of Higgs boson properties in the infinite top quark mass limit is the knowledge of the effective coupling between the Higgs bosons and g…
