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.

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 ...

Pseudoscalar meson-meson scattering

Nuclear Physics A, 1986
Abstract It is shown that an unmodified constituent model is not able to give agreement both with scattering lengths, either from PCAC or experiment, and with the experimental value of fπ. Therefore we propose a modified model. Assuming that only a fraction cM of a meson is well represented by the constituent model leads to a model which describes ...

A meson-baryon molecular interpretation for some $\Omega_{c}$Ωc excited states

, 2017
.We explore the possibility that some of the five narrow $\Omega_{c}$Ωc resonances recently observed at LHCb could correspond to pentaquark states, structured as meson-baryon bound states or molecules. The interaction of the low-lying pseudoscalar mesons
