A measurement of the τ-→K-π0ντ branching fraction has been made using 230.2 fb-1 of data recorded by the BABAR detector at the PEP-II e+e- collider, located at the Stanford Linear Accelerator Center (SLAC), at a center-of-mass energy √s close to 10.58 GeV. We measure B(τ-→K-π0ντ)=(0.416±0.003(stat)±0.018(syst))%.

Abstract
A measurement of the τ-→K-π0ντ branching fraction has been made using 230.2 fb-1 of data recorded by the BABAR detector at the PEP-II e+e- collider, located at the Stanford Linear Accelerator Center (SLAC), at a center-of-mass energy √s close to 10.58 GeV. We measure B(τ-→K-π0ντ)=(0.416±0.003(stat)±0.018(syst))%.
