Ronan McNulty (on behalf of the CDF collaboration)
TL;DR
This paper reports measurements of di-photon and photon plus heavy flavor jet production cross sections at 2 TeV, comparing results with QCD predictions and Pythia simulations, highlighting current statistical limitations.
Contribution
First measurements of di-photon and photon plus heavy flavor jet cross sections at Tevatron energy levels, with comparisons to theoretical models.
Findings
Inclusive di-photon cross-section agrees with NLO QCD
Photon+c to photon+b ratio measured and matches Pythia
Results are statistically limited but consistent with predictions
Abstract
The inclusive di-photon cross-section is measured in the central region and found to be in good agreement with NLO QCD predictions. Cross-sections are presented for events containing an energetic photon in addition to a heavy flavour jet. The ratio of photon+c to photon+b events is also measured. Results are currently statistically limited and in agreement with Pythia predictions.
