Open-beauty production in p Pb collisions at sqrt sNN=5 TeV: Effect of the gluon nuclear densities

Abstract : We present our results on open-beauty production in proton-nucleus collisions for the recent LHC p Pb run at View the MathML sourcesNN=5 TeV. We have analyzed the effect of the modification of the gluon PDFs in a nucleus at the level of the nuclear modification factor. Because of the absence of measurements in pp collisions at the same collision energy, View the MathML sourcesNN, we also propose the study of the forward-to-backward yield ratio in which the unknown proton-proton yield cancels. Our results are compared with the data obtained by the LHCb collaboration and show a good agreement.
