Diboson resonances within a custodially protected warped extra-dimensional scenario

open access: yes, 2015
We propose an interpretation of the diboson excess recently observed by the ATLAS and CMS collaborations in terms of Kaluza-Klein excitations of electroweak gauge bosons stemming from a realization of a warped extra-dimensional model that is protected by

Search for dark matter produced in association with a pair of bottom quarks in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
A search for dark matter (DM) particles produced in association with bottom quarks is presented. The analysis uses proton-proton collision data at a center-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV, corresponding to an integrated luminosity of 138 fb ...

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

open access: yesJournal 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

Total decay rates of B mesons at NNLO-QCD

open access: yesJournal of High Energy Physics
We update the Standard Model (SM) predictions for the lifetimes of the B +, B d and B s mesons within the heavy quark expansion (HQE), including the recently determined NNLO-QCD corrections to non-leptonic decays of the free b-quark.

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 ...

Towards a global analysis of the b → c u ¯ q $$ b\to c\overline{u}q $$ puzzle

open access: yesJournal of High Energy Physics
We study the nonleptonic decays B ¯ s 0 → D s ∗ + π − $$ {\overline{B}}_s^0\to {D}_s^{\left(\ast \right)+}{\pi}^{-} $$ and B ¯ 0 → D ∗ + K − $$ {\overline{B}}^0\to {D}^{\left(\ast \right)+}{K}^{-} $$ within the Weak Effective Theory (WET) up to mass ...
