  Sneutrino-antisneutrino oscillation can be observed at the LHC by studying a
charge asymmetry of the leptons in the final states. We demonstrate this in the
context of an anomaly-mediated supersymmetry breaking model which can give rise
to a large oscillation probability. The preferred region of the parameter space
is characterized by the presence of a sneutrino next-to-lightest supersymmetric
particle and a stau lightest supersymmetric particle. We show that the signals
studied here have certain correlations with the pattern of the sneutrino
oscillation.
