42. Euler-Lagrange equations for the high energy effective actions in QCD and gravity

Prof. Lev Lipatov (Petersburg Nuclear Physics Institute)

10/09/2015, 09:00

The theory of high energy processes in QCD is based on the gluon reggeization. In particular, Pomeron and Odderon are composite states of two and three reggeized gluons, respectively. We discuss the effective action and corresponding classical equations for quarks and gluons interacting with reggeized gluons. In the extended N=4 supersymmetric gauge model the Pomeron is dual to the...

10. Particle Production in Hybrid Formalism at NLO

Tolga Altinoluk

10/09/2015, 09:30

We reconsider the perturbative next-to-leading calculation of the single inclusive hadron production in the framework of the hybrid formalism, applied to hadron production in proton-nucleus collisions. We introduce the explicit requirement that fast fluctuations in the projectile wave function which only exists for a short time are not resolved by the target.This Ioffe time cutoff also...

11. Collisions of two projectiles on two targets in the BFKL approach

Prof. Mikhail Braun (Department of High Energy Physics, Saint-Petersburg State University, S. Petersburg, Russia)

10/09/2015, 10:30

High-energy collisions of two nucleons on two nucleons are studied in the BFKL approach in the leading approximation in ${\alpha }_s{N}_c$. Total cross-section as well as single and double inclusive cross-sections for gluon production are considered. Diagrams both with and without redistribution of colour are taken into account. It is found that intermediate BKP states consisting of 4...
