Current-current operator contribution to the decay matrix in -meson mixing at next-to-next-to-leading order of QCD
Marvin Gerlach, Ulrich Nierste, Pascal Reeck +2
We compute next-to-next-to-leading order perturbative corrections to the decay width difference of mass eigenstates and the charge-parity asymmetry in flavour-specific…
NNLO QCD corrections to in the system
Marvin Gerlach, Ulrich Nierste, Pascal Reeck +2
This report summarises recent advances made in the calculation of the NNLO QCD corrections to the width difference in the system. The inclusion of the e…
The width difference in the system at next-to-next-to-leading order of QCD
Marvin Gerlach, Ulrich Nierste, Vladyslav Shtabovenko +1
We extend the theoretical prediction for the width difference in the mixing of neutral mesons in the Standard Model to next-to-next-to-leading order in . To this ai…
Three-loop topology analysis of neutral B-meson mixing with tapir
Marvin Gerlach
Modern advances in particle physics depend strongly on the usage of reliable computer programs. In this context two issues become important: The usage of powerful algorithms to han…
The width difference in \bbm\ at order and beyond
Marvin Gerlach, Ulrich Nierste, Vladyslav Shtabovenko +1
We complete the calculation of the element of the decay matrix in mixing, , to order in the leading power of the Heavy Quark Expansion. To t…
: A tool for topologies, amplitudes, partial fraction decomposition and input for reductions
Marvin Gerlach, Florian Herren, Martin Lang
The demand for precision predictions in the field of high energy physics has dramatically increased over recent years. Experiments conducted at the LHC, as well as precision measur…
Two-loop QCD penguin contribution to the width difference in mixing
Marvin Gerlach, Ulrich Nierste, Vladyslav Shtabovenko +1
We consider two-loop QCD corrections to the element of the decay matrix in mixing, , 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 , where is the heavy quark mass, and compute several matching coefficien…
Wilson coefficients for Higgs boson production and decoupling relations to
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…
