The diffractive photoproduction of vector mesons is usually described by considering the two-gluon
~Pomeron! exchange, the nondiagonal parton distributions, and the contribution of the real part to the cross section. In ...

Neste trabalho de disserta¸c˜ao, investigamos os efeitos nucleares em processos de produ¸c˜ao
de quarkonium no Relativistic Heavy Ion Collider (RHIC) e no Large Hadron Collider
(LHC). Para tanto, consideramos o Modelo ...

In this Brief Report we estimate the influence of nonlinear gluon evolution in the production of prompt photons at the Large Hadron Collider (LHC) pp collider. We assume the validity of collinear factorization and consider ...

In this paper, we investigate the influence of nuclear effects in the production of gluinos in nuclear collisions at the Large Hadron Collider, and estimate the transverse momentum dependence of the nuclear ratios RpA = ...

We investigate heavy quark photoproduction based on the k'-factorization approach, focusing on the results from the saturation model. The deviations between the results using the unintegrated gluon distribution considering ...

Gluinos are expected to be one of the most massive sparticles (supersymmetric partners of usual particles) which constitute the Minimal Supersymmetric Standard Model (MSSM). The gluinos are the partners of the gluons and ...

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 ...

In this paper we estimate the influence of the shadowing effect and initial state parton energy loss in the quarkonium production at HERA-B. We analyze the xF behavior of the effective exponent α(xF) and present a comparison ...

The production of prompt photons at high energies provides a direct probe of the dynamics of strong interactions. In particular, one expects that it could be used to constrain the behavior of the nuclear gluon distribution ...

Models with essential non-perturbative QCD dynamics for the production of charmonium are extrapolated to give predictions of prompt J=Ã production at the LHC. Di®erences of up to an order of magnitude occurs, although the ...

Quarkonium hadroproduction in association with a photon at high energies provides a probe of the dynamics of the strong interactions as it is dependent on the nuclear gluon distribution. Therefore, it could be used to ...

Both hard and soft QCD dynamics are important in charmonium production, as presented here through a next-to-leading order QCD matrix element calculation combined with the color evaporation model. The observed xF and p⊥ ...
