Nuclear diffractive structure functions at high energies

Abstract: A future high-energy electron-ion collider would explore the non-linear weakly-coupled regime of QCD, and test the Color Glass Condensate (CGC) approach to high-energy scattering. Hard diffraction in deep inelastic scattering off nuclei will provide many fundamental measurements. In this work, the nuclear diffractive structure function F_{2,A}^D is predicted in the CGC framework, and the features of nuclear enhancement and suppression are discussed.

Forward particle production in proton-nucleus collisions at the LHC

Abstract: We present the current theory status on the particle production in the forward region in proton-nucleus (p+A) collisions based on the Color Glass Condensate framework. The cross-section expressed in a factorized form with the dipole amplitude which is related to the unintegrated gluon distribution. Energy dependence of the dipole amplitude is controlled by the nonlinear x-evolution equation and constrained by e+p scattering data at HERA. The transverse geometry of the target is modeled as an assembly of the nucleons distributed with the Woods-Saxon profile. We show our prediction for the nuclear modification factor of the hadron multiplicity in p+A reactions at the LHC energy.

Single Inclusive Hadron Production in DIS at Small $x$: Next to Leading Order Corrections

Abstract: We calculate the one-loop corrections to single inclusive hadron production in Deep Inelastic Scattering (DIS) at small $x$ in the forward rapidity region using the Color Glass Condensate formalism. We show that the divergent parts of the next to leading order (NLO) corrections either cancel among each other or lead to $x$ (rapidity) evolution of the leading order (LO) dipole cross section according to the JIMWLK evolution equation and DGLAP evolution of the parton-hadron fragmentation function. The remaining finite parts constitute the NLO ($\alpha_s$) corrections to the LO single inclusive hadron production cross section in DIS at small $x$.

Diffractive $\phi$ electroproduction with a holographic meson wavefunction

Abstract: We predict the cross-section for diffractive $\phi$ electroproduction within the dipole model, using a holographic meson wavefunction for the $\phi$. For the dipole cross-section, we use the Color Glass Condensate dipole model whose parameters are fitted to the latest 2015 combined HERA data on Deep Inelastic Scattering. Choosing a strange quark mass of $0.14$ GeV, we find good agreement with the available data.

Forward $J/\psi$ production in pA collisions: centrality dependence

Abstract: The nuclear suppression of forward $J/\psi$ production in high energy proton-nucleus collisions can be used as a probe of gluon saturation at small $x$. In an earlier work we studied this suppression in minimum bias collisions in the Color Glass Condensate formalism, relying on the optical Glauber model to obtain the dipole cross section of the nucleus from the one of the proton fitted to HERA DIS data. Here we study how the impact parameter dependence of this model can be used to compare our results with recent LHC data on the centrality dependence of this suppression.
