Abstract

Recent CDF data of the inclusive jet cross section shows threshold-like structured deviation, around transverse momentum E_T(j) ≈ 200-350 GeV. If this data is real, not just some statistical fluctuation, is it possible to interpret the anomaly in terms of virtual SUSY effects? The purpose of this note is to address this question. However, we find that virtual SUSY loop interference effects [near the threshold] are too small to explain the CDF data. Our main conclusion seems to be on the right track if we assume that the recent global analysis of improved parton distributions by Lai et al. is correct.
