dc.description.abstractWe report on the first search for Lambda -Lambda oscillations in the decay J=psi -> pK- Lambda & thorn; c:c: by analyzing 1.31 x 10(9) J=psi events accumulated with the BESIII detector at the BEPCII collider. The J=psi events are produced using e(+) e(-) collisions at a center of mass energy root s= 3.097 GeV. No evidence for hyperon oscillations is observed. The upper limit for the oscillation rate of Lambda to Lambda hyperons is determined to be P(Lambda)=[B(J/psi -> pK(-)Lambda + c:c.)/B(J/psi -> pK(-) Lambda & thorn; c:c.)] < 4.4 x 10(-6) corresponding to an oscillation parameter delta m(Lambda Lambda) of less than 3.8 x 10(-18) GeV at the 90% confidence level.en_US
