Lepton universality violation with lepton flavor conservation in B-meson decays [PDF]

open access: yesJournal of High Energy Physics, 2015
A bstractAnomalies in semileptonic B-meson decays present interesting patterns that might be revealing the shape of the new physics to come. Under the assumption that neutrino and charged lepton mass terms are the only sources of flavor violation and ...

Towards an automated tool to evaluate the impact of the nuclear modification of the gluon density on quarkonium, D and B meson production in proton–nucleus collisions [PDF]

open access: yesEuropean Physical Journal C, 2016
We propose a simple and model-independent procedure to account for the impact of the nuclear modification of the gluon density as encoded in nuclear collinear PDF sets on two-to-two partonic hard processes in proton–nucleus collisions.

B- and D-meson leptonic decay constants from four-flavor lattice QCD [PDF]

open access: yesPhysical Review D, 2018
We calculate the leptonic decay constants of heavy-light pseudoscalar mesons with charm and bottom quarks in lattice quantum chromodynamics on four-flavor QCD gauge-field configurations with dynamical $u$, $d$, $s$, and $c$ quarks. We analyze over twenty

B →P and B →V form factors from B-meson light-cone sum rules beyond leading twist [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractWe provide results for the full set of form factors describing semileptonic B-meson transitions to pseudoscalar mesons π, K, D¯$$ \overline{D} $$ and vector mesons ρ, K∗, D¯∗$$ {\overline{D}}^{\ast } $$.

Meson Condensation [PDF]

open access: yesParticles, 2019
We give a pedagogical review of the properties of the various meson condensation phases triggered by a large isospin or strangeness imbalance. We argue that these phases are extremely interesting and powerful playground for exploring the properties of ...

Sensitivity of lepton number violating meson decays in different experiments [PDF]

open access: yesPhysical Review D, 2019
We study the discovery prospect of different three body lepton number violating~(LNV) meson decays $M_{1}^{-}\to\ell_{1}^{-}\ell_{2}^{-}M_{2}^{+}$ in the framework of right handed~(RH) neutrino extended Standard Model~(SM).
