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…
Top quark mass effects in at two loops and off-shell Higgs interference
Ramona Gröber, Andreas Maier, Thomas Rauh
We consider top-quark mass effects in the Higgs-interference contribution to -boson pair production in gluon fusion. While this production mechanism is formally of next-to-next-…
Top quark mass dependence of the Higgs-gluon form factor at three loops
Joshua Davies, Ramona Groeber, Andreas Maier +2
We compute three-loop corrections to the Higgs-gluon form factor, incorporating the top quark mass dependence. Our method is based on the combination of expansions around the top t…
Bs mixing observables and Vtd/Vts from sum rules
Daniel King, Alexander Lenz, Thomas Rauh
We consider the effects of a non-vanishing strange-quark mass in the determination of the full basis of dimension six matrix elements for mixing, in particular we get for t…
Higher-order condensate corrections to masses, leptonic decay rates and sum rules
T. Rauh
With the recent completion of NNNLO results, the perturbative description of the system has reached a very high level of sophistication. We consider the non-perturbative correc…
Electroweak and non-resonant corrections to top-pair production near threshold at NNLO
Martin Beneke, Andreas Maier, Thomas Rauh +1
The top-quark mass can be determined with very high precision from a scan of the total cross section near the top-pair production threshold. We present…
Non-resonant and electroweak NNLO correction to the top anti-top threshold
Martin Beneke, Andreas Maier, Thomas Rauh +1
We determine the NNLO electroweak correction to the production cross section near the top-pair production threshold. The calculation includes non-reso…
Dimension-six matrix elements for meson mixing and lifetimes from sum rules
M. Kirk, A. Lenz, T. Rauh
The hadronic matrix elements of dimension-six operators are crucial inputs for the theory predictions of mixing observables and lifetime ratios in the and system.…
Reconstruction of top-quark mass effects in Higgs pair production and other gluon-fusion processes
Ramona Gröber, Andreas Maier, Thomas Rauh
We propose a novel method for the treatment of top-quark mass effects in the production of , , and final states in gluon fusion. We show that it is possible…
NNNLO determination of the bottom-quark mass from non-relativistic sum rules
Martin Beneke, Andreas Maier, Jan Piclum +1
The mass of the bottom quark can be determined with high precision from moments of the pair-production cross section sigma(e+ e- -> b bbar) near threshold. We present the first com…
Non-QCD contributions to top-pair production near threshold
Martin Beneke, Andreas Maier, Jan Piclum +1
The threshold scan of top pair production at a future lepton collider allows to determine several Standard Model parameters with very high precision. The recent completion of the t…
Higgs effects in top anti-top production near threshold in e+ e- annihilation
Martin Beneke, Andreas Maier, Jan Piclum +1
The completion of the third-order QCD corrections to the inclusive top-pair production cross section near threshold demonstrates that the strong dynamics is under control at the fe…
The inclusive decay b to ccs revisited
Fabian Krinner, Alexander Lenz, Thomas Rauh
The inclusive decay rate b to ccs is enhanced considerably due to perturbative QCD corrections. We recalculate the dominant part of the NLO-QCD corrections, because they cannot be…
D-meson lifetimes within the heavy quark expansion
Alexander Lenz, Thomas Rauh
Even if new data indicate that direct CP violation in D-meson decays is compatible with the standard model expectation, it has triggered a lot of interest, and charm phenomenology…
Short distance D-Dbar mixing
Markus Bobrowski, Alexander Lenz, Thomas Rauh
We review the status of Standard Model predictions for lifetimes and mixing rates of charmed mesons. It is shown that the short distance approach is able to reproduce tau(D^+)/tau(…
