A Technique for the Measurement of Tracking Efficiency
ORAL
Abstract
We present a method of obtaining tracking efficiency and asymmetry, as a function of lab momentum, using decays of tau leptons. The method obtains the efficiency and asymmetry directly from data. Background distributions are determined from Monte Carlo. We report on the results of a 2-dimensional binned $\chi^{2}$ fit to data recorded at the BaBar detector.
