A Search for Production of Scalar Top at the Fermilab Tevatron Collider
- New Mexico U.
We have searched for evidence of direct production of the scalar top quark in $$p\overline{p}$$ collisions at $$\sqrt{s}$$ = 1:8 TeV using the Collider Detector at Fermilab. We conducted the search assuming two different scenarios for decay of the scalar top. In the first, the scalar top quark decays into a bottom quark and a chargino with 100% probability. If this decay is not kinematically allowed, the scalar top quark decays into a bottom quark, a lepton, and a scalar neutrino. The branching ratios for this decay are 1/3 for each lepton type. The event signatures are the same for both decays so the searches were conducted using the same data sample. We find no evidence for signal in either decay channel and so set upper limits on the production cross section.
