New Physics in $s\to u\ell^-\bar\nu$: Interplay between semileptonic kaon and hyperon decays

, 2016
We review a novel model-independent approach to the analysis of new-physics effects in the $s\to u\ell^-\bar\nu$ transitions. We apply it to (semi)leptonic kaon decays and study their complementarity with pion and hyperon $\beta$ decays or with collider ...

Analyzing the semileptonic and nonleptonic B c → J/ψ, η c decays

Journal of High Energy Physics
This study focuses on the decay of the B c meson to S-wave charmonia. Starting with lattice inputs on B c → J/ψ form factors, we have obtained the B c → η c form factors using heavy quark spin symmetry (HQSS) relations between the associated form factors

Correlated study on some B c → P and B c → S wave channels in light of new inputs

Journal of High Energy Physics
This study investigates the decay modes of the B c meson, focusing on semileptonic and nonleptonic decay into S and P wave charmonia. The primary objective is to extract the shape parameter of the B c meson distribution amplitude through a data-driven ...

2016 Update of the $\mathrm{t\bar{t}H}$ Multilepton Analysis at $\sqrt{s} = 13$ TeV

, 2016
The latest results from the search for a Standard Model Higgs boson produced in association with a top quark pair ($\mathrm{t\bar{t}H}$) at $\sqrt{s} = 13$ TeV decaying to final states with multiple leptons is presented using the 2016 dataset from the ...

Challenging B ¯ s → D s ∗ $$ {\overline{B}}_{(s)}\to {D}_{(s)}^{\left(\ast \right)} $$ form factors with the heavy quark expansion

Journal of High Energy Physics
Recent publications by three lattice QCD collaborations have provided an unprecedented wealth of theoretical predictions for the B ¯ q → D q ∗ $$ {\overline{B}}_q\to {D}_q^{\left(\ast \right)} $$ form factors, for spectator flavours q = u/d and q = s. We

Nonperturbative parameters of inclusive Λ b decays from Small Velocity Sum Rules

Journal of High Energy Physics
We investigate the nonperturbative parameters entering the heavy quark expansion for the inclusive decay rates of the Λ b baryon, focusing on the kinetic term μ ̂ π 2 $$ {\hat{\mu}}_{\pi}^2 $$ and the Darwin term ρ ̂ D 3 $$ {\hat{\rho}}_D^3 $$ .
