Forward-backward asymmetry in $B\to D^{*}\ell\nu$: One more hint for scalar leptoquarks? / Carvunis, Alexandre (Annecy, LAPTH) ; Crivellin, Andreas (CERN ; Zurich U. ; PSI, Villigen) ; Guadagnoli, Diego (CERN ; Annecy, LAPTH) ; Gangal, Shireen (Annecy, LAPTH)
Experimental data have provided intriguing hints for the violation of lepton flavour universality (LFU), including $B\to D^{(*)}\tau\nu/B\to D^{(*)}\ell\nu$, the anomalous magnetic moment of the muon and $b\!\to\! s\ell^+\ell^-$ with a significance of $\!>3\,\sigma$, $>\!4\,\sigma$ and $>\!5\,\sigma$, respectively. Furthermore, in a recent re-analysis of 2018 Belle data, it was found that the forward-backward asymmetry ($\Delta A_{\rm FB}$) of $B \to D^{*}\mu\bar \nu$ vs $B\to D^{*}e\bar \nu$ disagrees with the SM prediction by $\approx\!\!4\,\sigma$, providing an additional sign of LFU violation.

On the effective lifetime of $B_s \to \mu \mu \gamma$ / Carvunis, Alexandre (Annecy, LAPTH) ; Dettori, Francesco (Cagliari U. ; INFN, Cagliari) ; Gangal, Shireen (Annecy, LAPTH) ; Guadagnoli, Diego (Annecy, LAPTH ; CERN) ; Normand, Camille (Annecy, LAPTH)
We consider the $B^0_s \to \mu^{+} \mu^{-} \gamma$ effective lifetime, and the related CP-phase sensitive quantity $A_{\Delta\Gamma_s}^{\mu \mu \gamma}$, as a way to obtain qualitatively new insights on the current $B$-decay discrepancies. Through a fit comparing pre- to post-Moriond-2021 data we identify a few theory benchmark scenarios addressing these discrepancies, and featuring large CP violation in addition. [...]

Higgs Production at NNLL$'$+NNLO using Rapidity Dependent Jet Vetoes / Gangal, Shireen (Tata Inst.) ; Gaunt, Jonathan R. (CERN) ; Tackmann, Frank J. (DESY) ; Vryonidou, Eleni (Nikhef, Amsterdam)
The rapidity-dependent jet veto observables $\mathcal{T}_{Bj}$ and $\mathcal{T}_{Cj}$ provide a tight jet veto at central rapidity, gradually transitioning to a loose veto at forward rapidities. They divide the phase space into exclusive jet bins in a different way to the traditional jet veto observable $p_{Tj}$, and are advantageous to use under harsh pile-up conditions. [...]
