Measurement of the strong coupling constant from inclusive jet production at the Tevatron pp collider.
Phys Rev Lett 88:4 (2002) 042001
Abstract:
We report a measurement of the strong coupling constant, alpha(s)(MZ), extracted from inclusive jet production in pp collisions at square root[s] = 1800 GeV. The QCD prediction for the evolution of alpha(s) with jet transverse energy ET is tested over the range 40Search for Gluinos and Scalar Quarks in pp¯ Collisions at s=1.8 TeV Using the Missing Energy plus Multijets Signature
Physical Review Letters American Physical Society (APS) 88:4 (2002) 041801
Abstract:
We have performed a search for gluinos (g) and scalar quarks (q) in a data sample of 84 pb(-1) of pp collisions at square root[s] = 1.8 TeV, recorded by the Collider Detector at 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 gluino masses below 195 GeV/c2 (95% C.L.), independent of the squark mass. For the case m(q) approximately m(g), gluino masses below 300 GeV/c2 are excluded.Search for gluinos and scalar quarks in pp collisions at square root[s] = 1.8 TeV using the missing energy plus multijets signature.

Abstract:
A search for gluinos and scalar quarks in a data sample of 84 pb -1 of pp̄ collisions at √s = 1.8 TeV was performed. The final state of large missing transverse energy and three or more jets was investigated. The data was compared with predictions of constrained supersymmetric models and gluinos masses below 195 GeV/c 2, independent of the squark mass were excluded.B Physics at the Tevatron: Run II and Beyond
