Abstract:

The results of a search for the direct production of Kaluza-Klein (KK) graviton modes using the rate of events with one or two energetic jets and large ET at the Collider Detector at Fermilab (CFD) were reported. The search was based on 84±4 pb-1 of integrated luminosity recorded with the CDF detector. The final state of large missing transverse energy and one or two high energy jets was also investigated. The calculation of graviton emission was based on the effective low-energy theory that was valid below the scale MD.

Abstract:

The search for pair production of scalar top quarks in an R-parity violating supersymmetry scenario in 106 pb-f of pp̄ collisions at √s = 1.8 TeV collected by the Collider Detector at Fermilab was discussed. It was found that in this mode each t1̃ decayed into a τ lepton and a b quark. The events with two τ's, one decaying leptonically and one decaying hadronically and two jets were searched. It was observed that a 95% confidence level lower limit was set on the t 1̄ mass at 122 GeV/c2 for Br(t1̃ → τb).
