104. Particle production in proton-nucleus collisions beyond leading order

Edmond Iancu (CEA/IRFU,Centre d'etude de Saclay Gif-sur-Yvette (FR))

The study of particle production in proton-nucleus collisions provides essential information about high-density effects (like gluon saturation) in the nuclear wavefunction. The corresponding cross-sections can in principle be computed within perturbative QCD, using the framework of the Color Glass Condensate. However, a recent calculation of single-inclusive hadron production at...

22. Moving to NLO accuracy in dilute-dense processes in the CGC picture

The color glass condensate (CGC) description of a high energy proton or nucleus, based on stong classical color fields, provides a way to understand the initial stages of a heavy ion collision in first principles QCD. In order to make this description quantitative, the color fields have to be studied by probing them with dilute probes. This talk concentrates on the description of two such...

90. Probing saturation with dijets at LHC

Piotr Kotko (Penn State University)

Dijet production in the gluon saturation regime provides
a unique probe for the gluonic content of hadrons.
This is because such process is, in general, sensitive to several
small-x transverse momentum dependent (TMD) gluon distributions.
I this talk I shall discuss a factorization-like approach which is suitable for production of dijet system with rather large transverse momenta.
Although it...

87. Sub-Eikonal Corrections to the Gluon Field of a Heavy Nucleus

Douglas Wertepny (Universidade de Santiago de Compostela)

While most initial-state calculations for heavy-ion collisions are performed in the asymptotic high-energy limit, real-world kinematics involve large but finite energies. Sub-eikonal corrections may therefore be important for calculating the initial conditions at RHIC or the LHC, especially those corrections which are enhanced by the size of the medium. Therefore, we study the first...
