Parallel Session II: Hard Probes in p+p and p+A Collisoions (II)
- Alexander Milov (Weizmann Institute of Science (IL))
QCD color coherence phenomena, like angular ordering, can be studied by looking at jet fragmentation. As the jet is fragmenting, it is expected to go through two different phases. First, there is QCD branching that is calculable in perturbative QCD. Next, the produced partons hadronize in an non-perturbative way in a hadronization process. The jet fragmentation can be efficiently studied using...
We discuss single inclusive hadron production from a high energy quark scattering off a strong target color field in the Color Glass Condensate formalism. Recent calculations of this process at the next-to-leading order accuracy have led to negative cross sections at large transverse momenta. We identify the origin of this problem as an oversubtraction of the rapidity divergence into the...
We include a resummation of large transverse momentum logarithms into the next-to-leading order Balitsky-Kovchegov equation. The resummed NLO evolution equation is shown to be stable, the evolution speed being significantly reduced by higher order corrections. The contributions from alpha_s^2 terms that are not enhanced by large logarithms are found to be numerically important close to...
Inclusive production of $J/\psi$ mesons at forward rapidity can be an important probe of saturation dynamics. We study this process in the Color Glass Condensate framework, in which a large x gluon from the proton probe splits into a quark pair and eikonally interacts with the target proton or nucleus probed at small x. We show that relying on the optical Glauber model to obtain the dipole...
