Quark-hadron duality at work: lifetimes of bottom baryons
James Gratrex, Alexander Lenz, Blaženka Melić +3
In the 1990s, very low experimental values for the lifetime ratio triggered a considerable amount of doubt in the applicability of the heavy quark expansion (HQE),…
Taming New Physics in with and
Alexander Lenz, Jakob Müller, Maria Laura Piscopo +1
Inspired by the recently observed tensions between the experimental data and the theoretical predictions, based on QCD factorisation, for several colour-allowed non-leptonic -me…
Disintegration of beauty: a precision study
Alexander Lenz, Maria Laura Piscopo, Aleksey V. Rusov
We update the Standard Model (SM) predictions for -meson lifetimes within the heavy quark expansion (HQE). Including for the first time the contribution of the Darwin operator,…
High precision in CKM unitarity tests in and decays
Alexander Lenz, Stephane Monteil
This article surveys the important questions attached to unitarity tests of the Cabibbo-Kobayashi-Maskawa matrix, with a focus on the direct determinations of the magnitude of CKM…
MUonE, muon and electroweak precision constraints within 2HDMs
Oliver Atkinson, Matthew Black, Christoph Englert +2
Two Higgs doublet models are attractive scenarios for physics beyond the Standard Model. In particular, lepton-specific manifestations remain contenders to explain the observed dis…
The Flavourful Present and Future of 2HDMs at the Collider Energy Frontier
Oliver Atkinson, Matthew Black, Christoph Englert +3
We study the intersection of flavour and collider physics for Two-Higgs-Doublet models of Type I and II. Drawing from the flavour precision-LHC exotics search complementarity, we a…
