Summary:

This note examines b-jet tagging at SDC, using semileptonic b {r arrow} eυ X electron decays. The main application for this tagging capability would be in the study of Top decays. Thus, we consider Top decays in a reasonable'' mass range (e.g. 110 < Mtop < 170). For completeness, we also consider inclusive QCD production of b-quarks. We are mainly interested in the effects of hadron calorimeter segmentation on the electron efficiency, assuming that similar algorithms are used for electron ID at SDC as at CDF. We review the following topics: kinematics of top decay; kinematics of semileptonic b-decay; effects of Had/EM cuts on electron ID, as a function of b-decay kinematics and calorimeter segmentation; overall efficiency for b-tagging from Top decay and inclusive b-production. We consider only the barrel region in our simulation, e.g. η < 1.4. 19 figs.
