Squark Gluino Mass Limits Revisited For Nonuniversal Scalar Masses

It is shown that if the sneutrino is the second lightest SUSY particle, then the decay products of squarks and gluinos produced at the TEVATRON collider tend to have i) more leptons, ii) smaller number of jets and iii) two or more carriers of 6ET . This may relax the existing limits on the squark and gluino masses. This effect is likely to be even more striking as these limits improve with accumulation of data. Numerical results for signal cross sections are presented and compared with the ones obtained without a light sneutrino. The possibilities of accommodating this scenario in models motivated by N = 1 SUGRA are discussed. 1 Permanent Address: Department of Physics, Jadavpur University, Calcutta 700 032, India. email:[email protected] email:[email protected]
