Next-to-next-to-leading QCD corrections to the -, -, and - lifetime ratios
Francesco Moretti, Ulrich Nierste, Pascal Reeck +1
The total decay widths of heavy mesons can be systematically calculated in terms of an expansion in the two parameters and , where denotes the heavy quark…
Complete next-to-next-to-leading order QCD corrections to the decay matrix in -meson mixing at leading power
Ulrich Nierste, Pascal Reeck, Vladyslav Shtabovenko +1
We compute next-to-next-to-leading order corrections to the decay width difference of mass eigenstates and the charge-parity (CP) asymmetry in flavour-specific decays…
QCD corrections to charged-current decays with Heavy Sterile Neutrinos in initial or final state and their impact on decays
Tim Kretz, Ulrich Nierste
Searches for a Heavy Sterile Neutrino profit from precise predictions of inclusive decay rates, entering predictions for branching fractions and lifetime. Once decay channels i…
CP Violation in Charmed Meson Decays into Final States with
Carolina Bolognani, Ulrich Nierste, Stefan Schacht +1
We derive Standard Model predictions for the CP asymmetries of singly-Cabibbo suppressed decays, where . Our predictions are based on the approximate SU…
Decay matrix of B-\bar{B} mixing: Mixing of dimension-seven operators into dimension-six operators under renormalization
Artyom Hovhannisyan, Ulrich Nierste
The precise measurement of the width difference ΔΓ_s among the mass eigenstates of the B_s-\bar{B}_s system requires the calculation of the corresponding decay matrix to order α_s/…
TeV-scale scalar leptoquarks motivated by B anomalies improve Yukawa unification in SO(10) GUT
Xiyuan Gao, Ulrich Nierste
It is common practice to explain deviations between data and Standard-Model (SM) predictions by postulating new particles at the TeV scale ad-hoc. This approach becomes much more c…
