Description

The measurement of Drell-Yan dilepton production at hadron colliders is a key channel to constrain the partonic content of hadrons. There exists no measurement at masses below 10 GeV/c and low transverse momentum at hadron colliders due to the dominating background from semileptonic decays of charm and beauty hadrons. The SemiCharmTag algorithm is presented to increase the signal-to-background ratio and to retrieve unbiased properties of leptons from semileptonic decays of charm hadrons. The impact of the introduction of such algorithm will be discussed in the context of the Run 3 data-taking period, comparing it to previous LHCb measurements.
