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

open access: yesJournal 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 ...

Study of form factors and observables in B c − $$ {B}_c^{-} $$ → D ¯ ∗ 0 ℓ − ν ¯ ℓ $$ {\overline{D}}^{\left(\ast \right)0}{\ell}^{-}{\overline{\nu}}_{\ell } $$ and B c − $$ {B}_c^{-} $$ → D (∗)− ℓ + ℓ − decays

open access: yesJournal of High Energy Physics
We investigate the decays B c − $$ {B}_c^{-} $$ → D ¯ ∗ 0 ℓ − ν ¯ ℓ $$ {\overline{D}}^{\left(\ast \right)0}{\ell}^{-}{\overline{\nu}}_{\ell } $$ and B c − $$ {B}_c^{-} $$ → D (∗)− ℓ + ℓ − within the Standard Model (SM), employing perturbative QCD (pQCD ...

On soft contributions to the B − → γ * form factors

open access: yesJournal of High Energy Physics
The photoleptonic decay B − → γ ℓ − ν ¯ $$ {B}^{-}\to \gamma {\ell}^{-}\overline{\nu} $$ is the simplest low-energy process that probes the substructure of the B meson, making it an excellent candidate to determine the parameters of B-meson light-cone ...

Searches for the Supersymmetric Partner of the Bottom Quark

open access: yes, 2004
We have performed a search for the scalar bottom quark from gluino decays in an R-parity conserving SUSY scenario with m(gluino) > m(sbottom), by investigating a final state of large missing transverse energy, with three or more jets, and some of them from the hadronization of b-quarks.

Tests of bottom quark CSM properties

open access: yes, 2017
We look for possible (partial) compositeness properties of the bottom quark according to the Composite Standard Model (CSM) concept in the same way this was previously done for Higgs boson and top quark. After looking at the direct form factor effects appearing in $e^+e^-\to b\bar b$ we analyze the more complex features of the $e^+e^-, gg, γγ\to b\bar ...
