A search for the nonconservation of lepton flavor in the decay tau(+/-)-> e(+/-)gamma has been performed with 2.07x10(8) e(+)e(-)->tau(+)tau(-) events collected by the BABAR detector at the SLAC PEP II storage ring at a center-of-mass energy near 10.58 GeV. We find no evidence for a signal and set an upper limit on the branching ratio of B(tau(+/-)-> e(+/-)gamma)< 1.1x10(-7) at 90% confidence level.

Abstract
A search for the nonconservation of lepton flavor in the decay tau(+/-)-> e(+/-)gamma has been performed with 2.07x10(8) e(+)e(-)->tau(+)tau(-) events collected by the BABAR detector at the SLAC PEP II storage ring at a center-of-mass energy near 10.58 GeV. We find no evidence for a signal and set an upper limit on the branching ratio of B(tau(+/-)-> e(+/-)gamma)< 1.1x10(-7) at 90% confidence level.File in questo prodotto:
