Track Counting b tagging algorithm

Complete: 0


This is a very simple tag, exploiting the long lifetime of B hadrons. It calculates the signed impact parameter significance of all good tracks, and orders them by decreasing significance. Its b tag discriminator is defined as the significance of the N'th track. It comes in two variations
N = 2 (High Efficiency)
N = 3 (High Purity)
