Nuclear Dependence Asymmetries in Direct Photon Production
We study the nuclear dependences of high-p T jet cross sections in one photon and one jet production in proton-nucleus collisions. We find that there exist asymmetries between the outgoing jets and photons. A convincing reason responsible for those asymmetries are demonstrated in perturbative QCD. Significant nuclear enhancements are also found in the inclusive jet cross sections. Anomalous nuc...
متن کاملHigh-energy resummation in direct photon production
We present the computation of the direct photon production cross-section in perturbative QCD to all orders in the limit of high partonic center-of-mass energy. We show how the high-energy resummation can be performed consistently in the presence of a collinear singularity in the final state, we compare our results to the fixed order NLO cross-section in MS scheme, and we provide predictions at ...
متن کاملNuclear dependence in direct photon production.
We calculate the nuclear dependence of direct photon production in hadronnucleus collisions. In terms of a multiple scattering picture, we factorize the cross section for direct photon production into calculable short-distance partonic parts times multiparton correlation functions in nuclei. We present the hadron-nucleus cross section as Aα times the hadron-nucleon cross section. Using informat...
متن کاملJ/ψ Production in Direct and Resolved Photon Collisions
The production of J/ψ mesons in photon photon collisions allows for a test of factorization in color-octet processes as predicted by NRQCD and observed at the Tevatron. We calculate the cross sections for J/ψ production with direct and resolved photons, including also the feed-down from χcJ and ψ ′ decays. Our NRQCD predictions are nicely confirmed by recent data from the DELPHI collaboration a...
متن کاملRecoil and Power Corrections in High-xT Direct-Photon Production
We study a class of nonperturbative corrections to single-inclusive photon cross sections at measured transverse momentum pT , in the large-xT limit. We develop an extension of the joint (threshold and transverse momentum) resummation formalism, appropriate for large xT , in which there are no kinematic singularities associated with recoil, and for which matching to fixed order and to threshold...
