Two-Gluon Correlations in Heavy-Light Ion Collisions: Energy and Geometry Dependence, IR Divergences, and -Factorization
Yuri V. Kovchegov, Douglas E. Wertepny
We study the properties of the cross section for two-gluon production in heavy-light ion collisions derived in our previous paper on the subject in the saturation/Color Glass Conde…
Sivers Function in the Quasi-Classical Approximation
Yuri V. Kovchegov, Matthew D. Sievert
We calculate the Sivers function in semi-inclusive deep inelastic scattering (SIDIS) and in the Drell-Yan process (DY) by employing the quasi-classical Glauber-Mueller/ McLerran-Ve…
Solution of the NLO BFKL Equation and a Strategy for Solving the All-Order BFKL Equation
Giovanni A. Chirilli, Yuri V. Kovchegov
We derive the solution of the NLO BFKL equation by constructing its eigenfunctions perturbatively, using an expansion around the LO BFKL (conformal) eigenfunctions. This method can…
Single-Spin Asymmetries in Semi-inclusive Deep Inelastic Scattering and Drell-Yan Processes
Stanley J. Brodsky, Dae Sung Hwang, Yuri V. Kovchegov +2
We examine in detail the diagrammatic mechanisms which provide the change of sign between the single transverse spin asymmetries measured in semi-inclusive deep inelastic scatterin…
