Abstract
Ultra-peripheral Vector Meson Production in CMS
Highlights
Within the Color Glass Condensate (CGC) framework, the hybrid formalism [1] is used to study single inclusive particle production at next-toleading order [2,3,4,5,6,7,8,9,10] and heavy-quark production [11] at forward rapidity
The dense target is treated in the CGC, i.e. it is defined as a distribution of strong color fields, which during the scattering transfer transverse momentum to the propagating partonic configuration
The usual approach is to calculate the cross section in the CGC, after which one takes the small dipole or correlation limit which corresponds to a leading-power expansion in the ratio p2t /Q2 of the hard scales with Λ2QCD p2t Q2
Summary
Within the Color Glass Condensate (CGC) framework, the hybrid formalism [1] is used to study single inclusive particle production at next-toleading order [2,3,4,5,6,7,8,9,10] and heavy-quark production [11] at forward rapidity. In this set-up, the wave function of the projectile proton is treated in the spirit. Non-perturbative models such as the McLerran–Venugopalan (MV) [23] or Golec-Biernat–Wüsthoff (GBW) model [24] can be used to write down analytical expressions
