We show how collectivity arises from a simple model of proton-nucleus collisions. The model consists of a projectile comprised of nearly collinear quarks coherently scattering off localized domains of color charge of a dense nuclear target.
We find that many of the features observed in light-heavy ion collisions at RHIC and the LHC often ascribed to collectivity are qualitatively reproduced....
The Lipatov's effective action for reggeized gluons, based on the gluodynamic Yang-Mills Lagrangian with external current for longitudinal gluons added, is considered. On the base of classical solutions the
one-loop corrections to this effective action in light-cone gauge are calculated. The Regge field theory (RFT) calculus for reggeized gluons, similar to the RFT introduced by Gribov, is...
We use the effective action for reggeized gluons exploring ideas of \cite{LipatovEff}. Using light-cone gauge, we consider a problem with
only one longitudinal gluon field in the equations of motion included. With the two reggeon fields presented in the approach,
the first reggeon field is defined as a LO value of the corresponding gluon field, whereas the second reggeon field
arises as a...
We investigate the spin-flip component of the Pomeron using the single spin asymmetry, $A_N(t)$, arising from Coulomb-nuclear interference (CNI) in small-angle elastic scattering.
The study of elastic proton-nucleus scattering is important because suppresses or excludes the contributions from iso-vector Reggeons which are predominantly spin-flip, and might have a significant impact on the...
