Pseudo-Efficiency (SVT-based) • Definition of pseudo-efficiency. • GTVL (GoodTracksVeryLoose) does not require DCH hits. • GTL (GoodTracksLoose) require 12 DCH hits. • Require 10 SVT hits • Are going to be used for systematic study • Tables are produced for Run5a • In the following plots • There are 4 plots each • pT dependence • Theta dependence • Multiplicity dependence • Phi dependence • is data, is MC or Data/MC ratio Babar Collaboration Meeting, K.
