ABSTRACT: This thesis presents the first measurement of the differential production cross section of a heavy flavor (bottom or charm) jet and direct photon at the Fermilab Tevatron. These measurements were performed using data recorded with the D0 detector from proton-antiproton collisions at a center of mass energy of sqrt(s) = 1.96 TeV. These results probe a kinematic range for the photon transverse momentum of 30 to 150 GeV and photon rapidity y

This thesis presents the first measurement of the differential production cross section of a heavy flavor (bottom or charm) jet and direct photon at the Fermilab Tevatron. These measurements were performed using data recorded with the D0 detector from proton-antiproton collisions at a center of mass energy of √s = 1.96 TeV. These results probe a kinematic range for the photon transverse momentum of 30

A measurement of differential cross sections for the production of a pair of isolated photons in proton-proton collisions at $\sqrt{s}=7\, \text {TeV} $ is presented. The data sample corresponds to an integrated luminosity of 5.0 $\, \text {fb}^{-1}$ collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross section for two isolated photons, with transverse energy above 40 and 25 $\, \text {GeV}$ respectively, in the pseudorapidity range $

A new measurement of the inclusive and differential production cross sections of J/[psi] mesons and b-hadrons in proton-antiproton collisions at √s = 1960 GeV is presented. The data correspond to an integrated luminosity of 39.7 pb−1 collected by the CDF Run II detector. The integrated cross section for inclusive J/[psi] production for all transverse momenta from 0 to 20 GeV/c in the rapidity range

Measurements of the di-photon cross section have been made in the central region and are found to be in good agreement with NLO QCD predictions. The cross section of events containing a photon and additional heavy flavor jet have also been measured, as well as the ratio of photon + b to photon + c. The statistically limited sample shows good agreement with Leading Order predictions.
