Squark and gluino mass limits in R-parity violating SUSY model from the Tevatron dilepton data

Abstract

We consider a R-parity-violating SUSY model, containing lepton-number-violating Yukawa couplings. Analysing the Tevatron dilepton data in terms of this model we get a lower mass limit of 100 GeV for squark and gluino. This is comparable to the corresponding limit obtained from the Tevatron missing- p T data in the R-conserving SUSY model. Taken together, they imply a lower squark/gluino mass limit of 100 GeV for any value of the relevant lepton-number-violating Yukawa couplings.
