Small-x TMD distributions initial condition: Nc-dependence and Gaussian approximations
Florian Cougoulic, Piotr Korcyl, Tomasz Stebel
We systematically derive expressions for ten small- Transverse Momentum Dependent (TMD) distributions in the Gaussian approximation, three in the quark-gluon sector and seven in…
Dijet production in DIS off a large nucleus at next-to-eikonal accuracy in a Gaussian model within the CGC framework
Pedro Agostini, Tolga Altinoluk, Néstor Armesto +3
We develop a Gaussian model to evaluate the decorated dipole and quadrupole operators that arise beyond the eikonal approximation in the Color Glass Condensate framework. While the…
Improving the solver for the Balitsky-Kovchegov evolution equation with Automatic Differentiation
Florian Cougoulic, Piotr Korcyl, Tomasz Stebel
The Balitsky-Kovchegov (BK) evolution equation is an equation derived from perturbative Quantum Chromodynamics that allows one to evolve with collision energy the scattering amplit…
Florian Cougoulic, Stéphane Peigné
We study the decomposition into irreducible representations (irreps) of the tensor product , where is the highest-dimensional irrep present in a…
Quark and Gluon Helicity Evolution at Small : Revised and Updated
Florian Cougoulic, Yuri V. Kovchegov, Andrey Tarasov +1
We revisit the problem of small Bjorken- evolution of the gluon and flavor-singlet quark helicity distributions in the shock wave (-channel) formalism. Earlier works on the s…
Cold nuclear matter effects on azimuthal decorrelation in heavy-ion collisions
Néstor Armesto, Florian Cougoulic, Bin Wu
The assumption of factorization lies at the core of calculations of medium effects on observables computable in perturbative Quantum Chromodynamics. In this work we examine this as…
