Model-independent bounds on new physics effects in non-leptonic tree-level decays of B-mesons
Alexander Lenz, Gilberto Tetlalmatzi-Xolocotzi
We present a considerably improved analysis of model-independent bounds on new physics effects in non-leptonic tree-level decays of B-mesons. Our main finding is that contributions…
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…
Computing Tools for the SMEFT
Editors, :, Jason Aebischer +22
The increasing interest in the phenomenology of the Standard Model Effective Field Theory (SMEFT), has led to the development of a wide spectrum of public codes which implement aut…
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…
Charming New -Physics
S. Jäger, M. Kirk, A. Lenz +1
We give a comprehensive account of the flavour physics of Beyond-Standard-Model (BSM) effects in transitions, considering the full set of 20 four-quark operator…
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…
within the Standard Model and beyond
Mikael Chala, Alexander Lenz, Aleksey V. Rusov +1
In light of the recent LHCb observation of CP violation in the charm sector, we review standard model (SM) predictions in the charm sector and in particular for . We get a…
