Single inclusive particle production cross sections in high energy hadron collisions at forward rapidity are an important benchmark process for the CGC picture of small x QCD. Recent calculations of this process have not led to a stable perturbative expansion for this quantity at high transverse momenta. We consider the quark channel production cross section using the new rapidity...
One of the striking results from the LHC has been the observation of collective behavior in high-multiplicity proton-proton and proton-nucleus collisions. The characteristic features of multi-particle correlation measurements are similar to those previously observed in collisions of heavy nuclei, and have been interpreted as a result of the hydrodynamic evolution of the produced QCD...
For ultrarelativistic proton-proton and proton-nucleus collisions, we perform an exploratory study of the contribution to the elliptic flow v2 coming from the orientation of the momentum of the produced particles with respect to the reaction plane. Via the CGC factorization valid at high energies, this contribution is related to the orientation of a color dipole with respect to its impact...
We consider correlations between produced quarks in p-A collisions in the framework of the Color Glass Condensate. We show that a quark-quark ridge that shows a dip at ∆η ∼ 2 relative to the gluon-gluon ridge. The origin of this dip is the short range (in rapidity) Pauli blocking experienced by quarks in the wave function of the incoming projectile. We observe that these correlations, present...
In this talk, I will discuss recent progress in understanding
multiparticle correlations in small systems from an initial state model.
In this model of eikonal quarks scattering off of a dense nuclear target
with localized domains of color charge, we are able to reproduce many of
the qualitative features observed in light-heavy ion collisions at RHIC
and the LHC which are often ascribed to...
I present the latest results from our work on simulating the early stages of heavy-ion collisions within the CGC picture in three dimensions. In our simulation we introduce an extra parameter for the longitudinal thickness of the nuclei and thereby explicitly break the boost invariance of the system. Consequently the full 3+1 dimensional classical Yang-Mills equations have to be solved...
