title = "Search for Lepton Flavor Violation in ? (3S) ?e ±µ±",
abstract = "We report on the first search for electron-muon lepton flavor violation (LFV) in the decay of a b quark and b antiquark bound state. We look for the LFV decay ?(3S)?e±µ± in a sample of 118 million ?(3S) mesons from 27 fb-1 of data collected with the BABAR detector at the SLAC PEP-II e+e- collider operating with a 10.36 GeV center-of-mass energy. No evidence for a signal is found, and we set a limit on the branching fraction B[?(3S)?e±µ±]<3.6×10-7 at 90% C. L. This result can be interpreted as a limit ?NP/gNP2>80 TeV on the energy scale ?NP divided by the coupling-squared gNP2 of relevant new physics (NP).",
