LHCb dimuon and charm mass distributions

[to restricted-access page]

Abstract

This note presents a collection of mass distributions for dimuons and charm hadrons collected by the LHCb experiment between 2011 and 2015. $1.2$ billion dimuons and $1.4$ billion charm hadrons have been collected during this data-taking period.

Figures and captions

Dimuon mass distribution divided by trigger groups (see text) for Run 1 and 2015 data. An inset plot with a zoom on the bottomonium region is shown on the top right corner.
