Description
We report the measurements of the branching fractions of the decay B(tau -> K npi0 nu), n=0,1,2,3, and B(tau -> pi npi0 nu), n=3,4 excluding the contributions that proceed through the decay of intermediate K0 and \eta mesons. The measurements are based on a data sample of 435 million tau pairs produced in e+e- collisions at and near the Y(4s) peak and collected with the BaBar detector in 1999--2008.
These measurements are substantial improvements of previous measurements and B(tau -> pi 4pi0 nu) is measured for the first time.
