Lepton-Flavor-Violation in tau-Production at BaBar - A Search for e+ e- to l+ tau-
We report on a search for the lepton-flavor-violating processes e{sup +}e{sup -} {yields} {mu}{sup +}{tau}{sup -} and e{sup +}e{sup -} {yields} e{sup +}{tau}{sup -}. The data sample corresponds to an integrated luminosity of 211 fb{sup -1} recorded by the BABAR experiment at the SLAC PEP-II asymmetric-energy B Factory at a center-of-mass energy of {radical}s = 10:58 GeV. We find no evidence for a signal and set the 95% confidence level upper limits on the cross sections to be {sigma}{sub {mu}{tau}} < 4:6 fb and {sigma}{sub e{tau}} < 10:1 fb. The ratios of the cross sections with respect to the dimuon cross section are measured to be {sigma}{sub {mu}{tau}} ={sigma}{sub {mu}{mu}} < 4:0x10{sup -6} and {sigma}{sub e{tau}}/{sigma}{sub {mu}{mu}} < 8.9 x 10{sup -6}.
