Search for new phenomena in CDF-I: Z(prime), W(prime) and leptoquarks

摘要

We present the latest results of CDF searches for Z(prime), W(prime) and leptoquarks. Using about 70pb(sup -1) data from 1992-95 CDF runs, we have searched for Z(prime) (yields) l(sup +)l(sup -), W(prime) (yields) WZ and pairs of second generation scalar leptoquark, S(sub 2). We find no evidence for these new particles, and set new mass limits at 95% CL. We exclude M(sub Z(prime)) < 650 GeV/c(sup 2), 205 < M(prime)(sub W) < 400 GeV/c(sup 2), and M(sub S2) < 180 GeV/c(sup 2) for (beta) = 1 and M(sub S2) < 141 GeV/c(sup 2) for (beta) = 0.5. Two interesting strange events are also shown.
