Abstract:
In the Collider Detector (CDF) at Fermilab National Accelerator Laboratory (FNAL), proton/anti-proton collisions yield results in instances where more than three hadronic jets are created with a significant imbalance in directional energy (missing transverse energy). This signature is characteristic of supersymmetry (SUSY), a theory that extends the Standard Model of particles and their interactions.This study concentrates on the effect of large tanβ on the two-dimensional parameter space determined by gluino mass (GeV/c2) and squark mass (GeV/c2). The supersymmetry data are generated with the Monte Carlo program ISAJET and subsequently simulated with a program, which reproduces the actual detector.We examine whether the existing search is extended to tanβ=30. In order to analyze data in an unbiased fashion, we are utilizing a method commonly known as the Blind Box. We find that for tanβ=30, we exclude at 95% C.L. masses of gluino less than 300 GeV/c2 and we also validate the result for other points in the parameter space. This is the first result in this channel at CDF that examines the high-tanβ SUSY scenario.
