Inclusive $B$ decays, lifetimes, and $∣ V_{c b} ∣$ : a unified heavy-quark expansion analysis

Matteo Fael, Ilija S. Milutin, Markus Prim +1

We present a global HQE analysis of inclusive semileptonic $B ˉ \to X_{c} l ν ˉ_{ℓ}$ moments, partial branching fractions, and $B^{+}$ , $B^{0}$ lifetime observables. Our fit setu…

Lepton flavour violation in rare $Λ_{b}$ decays

Marzia Bordone, Muslem Rahimi, K. Keri Vos

Lepton flavour violation (LFV) naturally occurs in many new physics models, specifically in those explaining the $B$ anomalies. While LFV has already been studied for mesonic decay…

QCD factorization of the four-lepton decay $B^{-} \to ℓ ν ˉ_{ℓ} ℓ^{(')} ℓ ˉ^{(')}$

Martin Beneke, Philipp Böer, Panagiotis Rigatos +1

Motivated by the first search for the rare charged-current $B$ decay to four leptons, $ℓ ν ˉ_{ℓ} ℓ^{(')} ℓ ˉ^{(')}$ , we calculate the decay amplitude with…

The Heavy Quark Expansion for Inclusive Semileptonic Charm Decays Revisited

Matteo Fael, Thomas Mannel, K. Keri Vos

The Heavy Quark Expansion (HQE) has become an extremely powerful tool in flavor physics. For charm decays, where the expansion parameters $α_{s} (m_{c})$ and $Λ_{QCD} / m_{c}$ are bigge…

Progress and challenges in the study of direct CP violation and $γ$ determinations: summary of CKM 2018 working group V

K. Keri Vos, Martin Sevior, Stefano Perazzini

In the study of CP violation within and beyond the Standard Model of particle physics, pure hadronic B decays are the key players. Improving the determination of the CKM angle $γ$ …

Theory of CP violation in B decays

K. Keri Vos

The study of CP violation in $B$ -meson decays has already reached a high level of precision, which will be pushed even higher in the future era of Belle-II and the LHCb upgrade. %I…

Five-particle contributions to the inclusive rare $B ˉ \to X_{s (d)} ℓ^{+} ℓ^{-}$ decays

Tobias Huber, Qin Qin, K. Keri Vos

We calculate tree-level contributions to the inclusive rare $B ˉ \to X_{s (d)} ℓ^{+} ℓ^{-}$ decays. At the partonic level they stem from the five-particle process $b \to s(d)…

$B_{s}^{0}$ - $B ˉ_{s}^{0}$ Oscillations as a New Tool to Explore CP Violation in $D_{s}^{\pm}$ Decays

Robert Fleischer, K. Keri Vos

CP violation in $B_{s}^{0}$ - $B ˉ_{s}^{0}$ oscillations is expected at the $1 0^{- 5}$ level in the Standard Model but could be enhanced by New Physics. Using $B_{s}^{0} \to D_{s}^{-} ℓ^{+} ν_{ℓ}$ …

Concurrent tests of Lorentz invariance in $β$ -decay experiments

K. K. Vos, H. W. Wilschut, R. G. E. Timmermans

Modern experiments on neutron and allowed nuclear $β$ decay search for new semileptonic interactions, beyond the ``left-handed'' electroweak force. We show that ongoing and planned…

Symmetry violations in nuclear and neutron $β$ decay

K. K. Vos, H. W. Wilschut, R. G. E. Timmermans

The role of $β$ decay as a low-energy probe of physics beyond the Standard Model is reviewed. Traditional searches for deviations from the Standard Model structure of the weak inte…

Testing Lorentz invariance in orbital electron capture

K. K. Vos, H. W. Wilschut, R. G. E. Timmermans

Searches for Lorentz violation were recently extended to the weak sector, in particular neutron and nuclear $β$ decay [1]. From experiments on forbidden $β$ -decay transitions stron…
