The transport coefficients of hot QCD plasma, in particular the bulk and shear viscosities, have attracted a lot of attention in recent years. They can be defined through the infrared limits of the corresponding spectral functions, which, however, are notoriously complicated to determine non-perturbatively. In this talk, I will present recent perturbative results for the bulk and shear thermal...

Plasma instabilities play important roles in thermalization processes of relativistic heavy-ion collisions. We study early-stage instabilities of non-Abelian plasma on the basis of two-particle irreducible(2PI) formalism. In this presentation, We focus on Nielsen-Olesen instability caused by homogeneous but time dependent color magnetic field. For this purpose, We perturbatively solve...

The proper description of the initial states of heavy ion collisions requires complete understanding of the partonic structure of the participants in the process. The essential role in the high-energy nuclear wave-functions of the target and projectile is played by the small-x gluons whose behavior and interactions are studied by the Color Glass Condensate effective theory. We extend the...

The amplitude for the collision of two hadrons with the lowest order
pomeron loop is calculated. Numerical calculations show that the loop
contribution to the amplitude begins to dominate the single pomeron
exchange at rapidities $8-10$. Full dependence of the triple-pomeron
vertex on intermediate conformal weights is taken into account.
