Catania Lepton Tag Riccardo Ranieri 2
Soft Lepton TagSoft Lepton Tag– Based on identification of the soft leptons from
semileptonic B-meson decays we studied only leptons=muonsleptons=muons case
– Efficiency of soft lepton tagging limited by the fraction of B-meson decays containing leptons (17%)
– Provide a valuable complement with respect to the impact parameter tagging
– Preliminary studies at parton level presented at bTau Workshop in Bari (28th May-1st June)
