PY - 2018 DA - 2018// TI - Measurement of the spectral function for the tau(-) -> K- K(S)v(tau) decay T2 - Phys. Rev. D JO - Physical Review D SP - 032010 EP - 11pp VL - 98 IS - 3 PB - Amer Physical Soc AB - The decay tau(-) -> K- K(S)v(tau) has been studied using 430 x 10(6) e(+) e(-) -> tau(+) tau(-) events produced at a center-of-mass energy around 10.6 GeV at the PEP-II collider and studied with the BABAR detector. The mass spectrum of the K- K-S system has been measured and the spectral function has been obtained. The measured branching fraction B(tau(-) -> K- K(S)v(tau)) = (0.739 +/- 0.011 (stat) +/- 0.020 (syst)) x 10(-3) is found to be in agreement with earlier measurements.
