Preliminary Measurement of B(tau- ---> K- pi0 nu/tau) Using the BaBar Detector

Conference ·
OSTI ID:878875
A preliminary measurement of the branching fraction {Beta}({tau}{sup -} {yields} K{sup -}{pi}{sup 0}{nu}{sub {tau}}) is made using 124.4 fb{sup -1} of e{sup +}e{sup -} collision data provided by the PEP-II accelerator, operating primarily at {radical}s = 10.58 GeV, and recorded using the BABAR detector. They measure: {Beta}({tau}{sup -} {yields} K{sup -} {pi}{sup 0}{nu}{sub {tau}}) = (0.438 {+-} 0.004(stat) {+-} 0.022(syst))%. This result is the world's most precise measurement of this branching fraction to date and is consistent with the world average.
