Description

The Collider Detector at Fermilab (CDF) is a multi-purpose detector designed to study proton-antiproton collisions at center-of-mass energies of 1.96 TeV/c{sup 2}. One of the most importatn components of CDF is the silicon tracking detector. A detailed description of the testing and construction of the CDF silicon tracker is presented. Measurements of the tracking efficiency of the completed detector are also provided. Using 36 pb{sup -1} of the J/{psi} data sample collected by CDF between February and October 2002, the inclusive B {yields} J/{psi} X cross-section is measured in p{bar p} interactions at {radical}s = 1.96 TeV/c{sup 2}. The fraction ... continued below

Description

The Collider Detector at Fermilab (CDF) is a multi-purpose detector designed to study proton-antiproton collisions at center-of-mass energies of 1.96 TeV/c{sup 2}. One of the most importatn components of CDF is the silicon tracking detector. A detailed description of the testing and construction of the CDF silicon tracker is presented. Measurements of the tracking efficiency of the completed detector are also provided. Using 36 pb{sup -1} of the J/{psi} data sample collected by CDF between February and October 2002, the inclusive B {yields} J/{psi} X cross-section is measured in p{bar p} interactions at {radical}s = 1.96 TeV/c{sup 2}. The fraction of J/{psi} events arising from the decay of b hadrons is extracted using an unbinned maximum likelihood fit to the decay length of the J/{psi} candidates. The p{sub T} dependent differential cross section for inclusive B {yields} J/{psi} X events with rapidity |y| < 0.6 is obtained by combining the B-fraction result with a measurement of the J/{psi} differential cross-section. For 2.0 < p{sub T}(J/{psi}) < 17.0 GeV/c, the integrated B {yields} J/{psi} X cross-section is measured to be {sigma}(J/{psi}, B) {center_dot} {Beta}(J/{psi} {yields} {mu}{mu}) = 16.02 {+-} 0.24(stat){sub -2.20}{sup +2.26}(syst) nb.
