a PhD in Particle Physics. I am measuring the branching fraction and
hadronic mass distribution of the decay tau -> Ks pi nu using tau pairs
produced at the BaBar experiment at the Stanford Linear Accelerator Center.
Events are selected based on a variety of kinematics criteria that are
optimized in order to maximise the signal significance. Corrections to the
raw branching fraction are derived based on comparisons of simulated and
real data samples. The Ks pi mass spectrum is then fitted and Standard Model
parameters m_s and V_us are extracted from this fit.
