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 ...

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

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 ...

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 $$ {\hat{\rho}}_D^3 $$ .

Review of D Semi-leptonic Decays

, 2012
Semi-leptonic D decays continue to play an important role in the field of flavor physics. During this presentation, recent measurements from pseudo-scalar to pseudo-scalar modes, pseudo-scalar to vector modes, and rare modes will be discussed. These results are important for many purposes, such as validating the machinery of lattice QCD, extracting CKM

Disentangling new physics in K → πν ν ¯ $$ K\to \pi \nu \overline{\nu} $$ and B → K K ∗ ν ν ¯ $$ B\to K\left({K}^{\ast}\right)\nu \overline{\nu} $$ observables

Journal of High Energy Physics
We investigate the possibility of disentangling different new physics contributions to the rare meson decays and through kinematic distributions in the missing energy .
