Inelastic J/ψ photoproduction in electron-proton collisions at HERA

Yip, Timothy C. Y. January 1996 (has links)
The development of a neural network based electron finder designed for the ZEUS calorimeter is described. A study of elastic and inelastic J/ψ meson production in electron-proton collisions at HERA using the ZEUS detector is presented. During the 1993 and 1994 running periods, the ZEUS detector collected ~ 500 nb<sup>-1</sup> and ~ 3 pb<sup>-1</sup> of data respectively. The direct inelastic J/ψ photoproduction cross-section is measured for both running periods and an attempt is made to extract the gluon density inside the proton using the 1994 inelastic J/ψ sample.

Relative transverse momentum distributions of bottom hadrons produced in 1.96 TeV proton-antiproton collisions

Roy, Philippe, 1983- January 2008 (has links)
Fragmentation is the process by which bare quarks dress themselves up as hadrons. Since we cannot get reliable calculations of this process using perturbative quantum chromodynamics, the fragmentation properties of quarks must be obtained empirically. We report on the signal extraction and relative transverse momentum (pT) spectrum determination that will lead to a high precision measurement of relative fragmentation fractions of b quarks into B hadrons, in 1.96 TeV pp&macr; collisions. Using 1.9 fb-1 of data taken with the CDF-II detector, we fully reconstruct 473 +/- 42 B0s&rarr;D-sp + , 15206 +/- 203 B0 &rarr; D-pi+, 1483 +/- 45 B0 &rarr; D*-pi + and 4444 +/- 297 L0b&rarr;L+ cp- candidate decays. In order to reduce systematic uncertainties, ratios of pT spectra are reported. We find that Bs and B0 mesons are produced with similar pT and &Lambda;b baryons are produced with lower pT than B0 mesons. Our results are consistent with previous CDF measurements suggesting a difference between fragmentation processes observed at lepton and hadron colliders.
