Investigating the high energy QCD approaches for prompt photon production at the LHC

We investigate the rapidity and transverse momentum distributions of the prompt photon production at the CERN LHC energies considering the current perturbative QCD approaches for this scattering process. Namely, we compare the predictions from the usual NLO pQCD calculations to the the color dipole formalism, using distinct dipole cross sections. Special attention is paid to parton saturation m...

Quarkonium Production at the LHC

More than 30 years after the discovery of the J/ψ, its production mechanism is still poorly understood. With the LHC data it will be possible to study quarkonia up to very high transverse momenta and with high statistics. In this note we discuss experimental aspects of J/ψ and Υ(1S) production at the LHC. In particular, we investigate the sensitivity of a general purpose LHC detector to observa...

Charmonium production at the LHC

The analyses of large transverse momentum charmonium production at the Tevatron have shown that fragmentation of gluons is an important production mechanism. We study large-pT charmonium production in pp collisions at the LHC, and find that due to the copious gluon production at this energy, the gluon fragmentation contribution completely overwhelms the fusion contribution and the charm quark f...

Photon Production at the Lhc

We review the lastest results on photon production at the LHC by the ATLAS and CMS experiments obtained in proton-proton collisions with a center of mass energy of 7 TeV in 2010 and 2011, corresponding to a maximum integrated luminosity of 5 fb−1. We compare the prompt photon and photon-jet differential cross sections to theoretical predictions and discuss their impact on the parton distributio...

Prompt Photon Production at the Tevatron

In Leading Order (LO) prompt photons originating in the hard interaction between two partons are produced mainly via quark-gluon Compton scattering (qg → qγ) or quark–anti-quark annihilation (qq̄ → gγ). Studies of direct photons with large transverse momenta, pγT , provide precision tests of perturbative QCD (pQCD) as well as information on the distribution of partons within protons, particularl...
