Angular pattern of minijet transverse energy flow in hadron and nuclear collisions

A. V. Leonidov, D. M. Ostrovsky

The azimuthal asymmetry of minijet system produced at the early stage of nucleon-nucleon and nuclear collisions in a central rapidity window is studied. We show that in pp collisio…

Minijet transverse energy production in the next-to-leading order in hadron and nuclear collisions

A. V. Leonidov, D. M. Ostrovsky

The transverse energy flow generated by minijets in hadron and nuclear collisions into a given rapidity window in the central region is calculated in the next-to-leading (NLO) orde…

Influence of source evolution on particle correlations

I. V. Andreev

Modification of the particles in the course of the source evolution is considered. Influence of this effect on multiplicities and correlations of the particles is displayed, includ…

Fermi spectra and their gauge invariance in hot and dense Abelian and non-Abelian theories

O. K. Kalashnikov

The one-loop Fermi spectra (one-particle and collective ones) are found for all momenta in the -approximation and their gauge invariance in hot and dense Abelian and non-Abeli…

Compton Scattering on Pion and Pion Polarizabilities

L. V. Fil'kov, V. L. Kashevarov

The Compton scattering on a charged pion is studied using the dispersion relations. Unknown mass, full width and decay width into γγof the sigma meson are found from a fit to the e…

Abelian Landau-Pomeranchuk-Migdal effects

I. M. Dremin, C. S. Lam

It is shown that the high-energy expansion of the scattering amplitude calculated from Feynman diagrams factorizes in such a way that it can be reduced to the eikonalized form up t…

Fragmentation and Multifragmentation of 10.6A GeV Gold Nuclei

EMU01-Collaboration

We present the results of a study performed on the interactions of 10.6A GeV gold nuclei in nuclear emulsions. In a minimum bias sample of 1311 interac- tions, 5260 helium nuclei a…

Energy dependence of ratios of multiplicities and their slopes for gluon and quark jets

I. M. Dremin

The difference between the ratio of multiplicities and the ratio of their derivatives on energy for gluon and quark jets is calculated up to next-to-next-to leading order of pertur…

Unitarization of Gluon Distribution in the Doubly Logarithmic Regime at High Density

Jamal Jalilian-Marian, Alex Kovner, Andrei Leonidov +1

We analyze the general nonlinear evolution equations for multi gluon correlators derived in hep-ph/9709432 by restricting ourselves to a double logarithmic region. In this region o…

Entanglement of Fock-space expansion and covariance in light-front Hamiltonian dynamics

N. C. J. Schoonderwoerd, B. L. G. Bakker, V. A. Karmanov

We investigate in a model with scalar ``nucleons'' and mesons the contributions of higher Fock states that are neglected in the ladder approximation of the Lippmann-Schwinger equat…

One-particle and collective electron spectra in hot and dense QED and their gauge dependence

O. K. Kalashnikov

The one-particle electron spectrum is found for hot and dense QED and its properties are investigated in comparison with the collective spectrum. It is shown that the one-particle…

Low-Energy Compton Scattering of Polarized Photons on Polarized Nucleons

D. Babusci, G. Giordano, A. I. L'vov +2

The general structure of the cross section of scattering with polarized photon and/or nucleon in initial and/or final state is systematically described and exposed through inv…

Photon and electron spectra in hot and dense QED

O. K. Kalashnikov

Photon and electron spectra in hot and dense QED are found in the high temperature limit for all $|\q|$ using the Feynman gauge and the one-loop self-energy. All spectra are split…
