TL;DR
This paper uses the DGLAP improved color dipole model to successfully describe existing direct photon data and predicts their transverse momentum distribution at LHC energies.
Contribution
It extends the color dipole approach to predict direct photon spectra at LHC, providing new theoretical insights.
Findings
Good agreement with RHIC and Tevatron data
Predicted photon spectra at LHC energies
Validated the DGLAP improved color dipole model
Abstract
The DGLAP improved color dipole approach provides a good description of data for inclusive direct photon spectra at the energies of RHIC and Tevatron. Within the same framework we predict the transverse momentum distribution of direct photons at the CERN LHC energies.
