Heavy sterile neutrinos in $B$ decays and new QCD corrections to their semi-hadronic decay rates

Tim Kretz

In modern experiments on flavour physics it is possible to search for the decays of $B$ or $D$ mesons or $τ$ leptons into final states with heavy neutrinos $N$ (a.k.a. heavy neutra…

$b \to c$ semileptonic sum rule: Extension to angular observables

Motoi Endo, Syuhei Iguro, Tim Kretz +2

Lepton flavor universality is a key prediction of the Standard Model of particle physics and any violation of it immediately indicates the existence of new physics. Given the recen…

Model independent bounds on heavy sterile neutrinos from the angular distribution of $B \to D^{*} ℓ ν$ decays

Florian U. Bernlochner, Marco Fedele, Tim Kretz +2

In this paper we study the bounds that can be inferred on New Physics couplings to heavy sterile neutrinos $N$ from the recent measurements performed by the Belle collaboration of…
