T. Affolder et al., Search for scalar top and scalar bottom quarks in (p)over-barp collisions at j root s=1.8 TeV, PHYS REV L, 84(25), 2000, pp. 5704-5709
We have searched for direct pair production of scalar top and scalar bottom
quarks in 88 pb(-1) of p (p) over bar collisions at root s = 1.8 TeV with
the CDF detector. We looked fur events with a pair of heavy flavor jets and
missing energy, consistent with scalar top (bottom) quark decays to a char
m (bottom) quark and a neutralino. The numbers of events that pass our sele
ctions show no significant deviation From standard model expectations. We c
ompare our results to the next-to-leading order scaler quark production cro
ss sections to exclude regions in scalar quality-neutralino mass parameter
space.
