Title: Photon and neutral pion production in pp and Pb-Pb collisions at LHC energies in the ALICE experiment
Author: Kurashvili, Podist
Contributor: Kurashvili, Podist (pacrepositoryorg)
Subject: Protons ; Photons ; Collisions ; Pions
Description: We present the results for direct photon and neutral pion production obtained from proton-proton and lead-lead collisions in the ALICE experiment. Measurement of neutral pions in pp collisions allows to test the validity of QCD-inspired models. The study of neutral pion yields in Pb-Pb collisions permits to study the medium-induced suppression relative to the pp case. The yield of direct photons is compared to perturbative QCD calculations. In the case of central Pb-Pb collisions the observed excess of photons below 4 GeV/c is used to find the effective temperature of the matter.

Title: Quantum Hall Effect and Dyson-Swinger Equation
Author: Kurashvili, Podist
Contributor: Kurashvili, Podist (pacrepositoryorg)
Subject: Electromagnetism ; Free Electrons ; Green'S Functions ; Quantum Hall Effect ; Mathematical Analysis ; Perturbation Theory ; Approximation ; Electrodynamics
Description: In this paper we make attempt to obtain a description of the Quantum Hall Effect (both integer and fractional) by means of electron's Green functions of three-dimensional (planar) electrodynamics. We show that expression for the free electron propagator yields an integer number for the second Chern-Simons term, that corresponds to the quantized Hall conductivity in the approximation of non-interacting particles for integer filling factors, when there exists a gap for all excitations in the system. Then we try to check correspondence between fractional case and "interacting" Green functions, so it requires taking into consideration "full-fledged" propagators, including interactions. We are going to obtain them from Dyson-Swinger equations. We attempt to reach out from the perturbation theory regime using a specific method, called scale approximation. Our solutions are found in general gauge.
