breaking effects in and meson lifetimes
Daniel King, Alexander Lenz, Thomas Rauh
In the heavy quark expansion (HQE) of the total decay rates of and mesons non-perturbative matrix elements of four quark operators are arising as phase space enhanced…
Two-loop anomalous dimension for the resummation of non-global observables
Thomas Becher, Thomas Rauh, Xiaofeng Xu
The soft radiation emitted in jet cross sections can resolve the directions and colors of individual hard partons, leading to a complicated pattern of logarithmically enhanced term…
Revisiting Inclusive Decay Widths of Charmed Mesons
Daniel King, Alexander Lenz, Maria Laura Piscopo +3
Determining for the first time the Darwin operator contribution for the non-leptonic charm-quark decays and using new non-perturbative results for the matrix elements of fou…
Padé approach to top-quark mass effects in gluon fusion amplitudes
Joshua Davies, Ramona Gröber, Andreas Maier +2
Gluon fusion processes like single and double Higgs production exhibit slow convergence and pose severe computational challenges. We show how the top-quark mass dependence of the v…
and from -mixing -- Addendum to " mixing observables and from sum rules"
Daniel King, Matthew Kirk, Alexander Lenz +1
In this addendum to " mixing observables and from sum rules" \cite{King:2019lal} we study the impact of the recent improvements in the theoretical precision…
theory precision confronts flavour anomalies
Luca Di Luzio, Matthew Kirk, Alexander Lenz +1
Based on recent HQET sum rule and lattice calculations we present updated Standard Model predictions for the mass differences of neutral mesons: $ΔM_s^{\rm SM} = \left(18.4^{+0…
