Abstract:

We present a study of events with W bosons and hadronic jets produced in p̄p collisions at a center of mass energy of 1.8 TeV. The data consist of 51400 W → e ν decay candidates from 108 pb-1 of integrated luminosity collected using the CDF detector at the Fermilab Tevatron collider. Cross sections and jet production properties have been measured for W + ≥ 1 to ≥ 4 jet events. The data compare well to predictions of leading-order QCD matrix element calculations with added gluon radiation and simulated parton fragmentation.

Abstract:

Neutron Higgs bosons produced in association with `b' quarks were investigated. Experimental results showed that there was no evidence for the existence of such a signal. The data was interpreted using the Neutral Higgs sector of the supersymmetric extension of standard model. The lower mass limits for neutral Higgs bosons were derived for tanβ values in excess of 35.

Abstract:

The charmonium system was studied by measuring the relative cross sections of the Xc1 and Xc2 produced in pp collisions at √ s = 1.8 TeV. As a result, the ratio of production cross sections was established.

Abstract:

The ratio of the branching fraction from particle collisions were measured. The data was recorded by the Collider Detector at fermilab during the Tevatron run. The measured values were in agreement with the standard model predictions. The measurements yielded a limit on the Cabibbo-Kobayashi-Maskawa quark mixing matrix element.
