Photon + Heavy Flavor Production using SVT

Document(s) Web Page       Public Note       Phys. Rev. D81, 052006 (2010) Contact(s) M. Campanelli Abstract We present a study of the photon + b-jet production at the Tevatron in the CDF II detector. The analysis is performed with a dataset that makes use of the on-line tracking reconstruction provided by the SVT to enhance the b content and lower the photon Et threshold with respect to the inclusive photon sample. The trigger efficiency is measured directly from data. We considere events with Et(γ)>12 GeV, |η(γ)|<1.1, Et(j)>20 GeV, |η(j)|<1.5, and Δ R(jγ)>0.7, and measure the total cross section as well as the differential cross sections as a function of photon Et and b-jet Et.

Photon + Heavy Flavor Production

Document(s) Web Page       Public Note Contact(s) R. McNulty and T. Shears Abstract Measurements of photon + b jet production, obtained with a dataset of 340 pb-1, are presented. Cross-sections are measured for all events containing photons with transverse energy above 26 GeV, and differentially in bins of photon transverse energy between 26 and 70 GeV. Our results agree with leading order predictions. Comments Last Update: July 2006       Dataset: 340 pb-1
