Predictions for -baryon lifetimes at NNLO-QCD
Alexander Lenz, Maria Laura Piscopo, Aleksey V. Rusov
Motivated by recent and forthcoming experimental progress, we provide updated predictions for the total decay rates of -baryons, their lifetime ratios and their lifetimes normal…
-meson decay width up to corrections within and beyond the Standard Model
Martin Lang, Alexander Lenz, Ali Mohamed +2
Starting from the most general effective Hamiltonian describing non-leptonic -quark decays , we compute analytic expressions for all matching c…
Charm physics
David Friday, Evelina Gersabeck, Alexander Lenz +1
50 years after the discovery of the first charmed particle, charm physics continues to be an extremely lively field of research and a cornerstone in particle physics. The study of…
Total decay rates of mesons at NNLO-QCD
Manuel Egner, Matteo Fael, Alexander Lenz +4
We update the Standard Model (SM) predictions for the lifetimes of the , and mesons within the heavy quark expansion (HQE), including the recently determined NNLO-…
HQET sum rules for matrix elements of dimension-six four-quark operators for meson lifetimes within and beyond the Standard Model
Matthew Black, Martin Lang, Alexander Lenz +1
Theory predictions of heavy-hadron lifetime ratios critically depend on precise determinations of the dimension-six spectator effects arising from the double insertion of the weak…
Towards a SM prediction for CP violation in charm
Alexander Lenz, Maria Laura Piscopo, Aleksey V. Rusov
We provide an overview of the current experimental and theoretical status of charm CP violation and discuss recent progress in obtaining a Standard Model prediction for $Δa_{\rm CP…
Lifetimes of -hadrons and mixing of neutral -mesons: theoretical and experimental status
Johannes Albrecht, Florian Bernlochner, Alexander Lenz +1
In this article, we review the current status of -mixing and -hadron lifetimes both from experimental and theoretical points of view. Furthermore, we discuss the phenomenolog…
Two body non-leptonic decays from LCSR and implications for
Alexander Lenz, Maria Laura Piscopo, Aleksey V. Rusov
Motivated by the recent measurements of CP violating effects in singly Cabibbo suppressed decays, we revisit the theoretical predictions of these channels. Using up-to-date v…
