Description
We present a search for decay of the Y(1S) meson into undetectable
final states, using a sample of Y(3S) mesons collected at
the PEP-II/BaBar B-factory. We tag the decay of the Y(3S) into
the Y(1S) through a pair of charged pions, and measure the rate at
which the Y(1S) decays into particles which do not interact with
the BaBar detector. Furthermore, we present a search for
charged lepton-flavor violating decays Upsilon --> e+ tau- and
Upsilon --> mu+ tau- which probes BSM contributions at the TeV
mass scales.
