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.

Production of χc1 and χc2 in pp̄ collisions at √s = 1.8 TeV

Physical Review Letters 86:18 (2001) 3963-3968

Authors:

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.

First measurement of the ratio B(t → Wb)/B(t → Wq) and associated limit on the Cabibbo-Kobayashi-Maskawa element ΙVtbΙ

Physical Review Letters 86:15 (2001) 3233-3238

Authors:

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.
