Track Probability B-Tagging

Complete: 1

Algorithm Description

For each track associated to a jet we apply some quality cuts, if passed, we compute the 2D and 3D IP. Then we have an object that given a track associate it to the correct category (now based on P,Eta,Nhit,Npixhit, chisquare). To each category a different PDF for the resolution function of IP-significance of tracks coming from Prim. Vtx is associated. With the given PDF and the 2D or 3D I.P. the probability of each track to originate from PV is computed (one prob for 2D and one for 3D) A Jet probability is then computed from the single track probs using some formula.
