Search for gluinos and scalar quarks in pp̄ Collisions at √s = 1.8 TeV using the missing energy plus multijets signature
2002
We have performed a search for
gluinos((g)
over
tilde) and scalar quarks ((q)
over
tilde) in a data sample of 84 pb(-1) of p (p)
overbar collisions at roots = 1.8 TeV, recorded by the
Collider Detectorat
Fermilab. We investigate the final state of large missing transverse energy and three or more jets, a characteristic signature in
R-parity-conserving supersymmetric models. The analysis has been performed "blind," in that the inspection of the signal region is made only after the predictions from standard model backgrounds have been calculated. Comparing the data with predictions of constrained supersymmetric models, we
exclude
gluinomasses below 195 GeV/c(2) (95% C.L.), independent of the squark mass. For the case m((q)
overbar) approximate to m((g)
over
tilde),
gluinomasses below 300 GeV/c(2) are
excluded.
