Effective action for QED with fermion self-interaction in D=2 and D=3 dimensions
(American Physical Soc, 2002-06-15)
In this work we discuss the effect of the quartic fermion self-interaction of Thirring type in QED in D=2 and D=3 dimensions. This is done through the computation of the effective action up to quadratic terms in the photon ...
Off-Diagonal Quark Distributions in Pions in the Effective Single-Instanton Approximation
(2000-12-01)
Nonperturbative functions that parametrize off-diagonal hadronic matrix elements of the light-cone leading-twist quark operators are considered. These functions are calculated within the proposed relativistic quark model ...

IDEAS OF FOUR-FERMION OPERATORS IN HADRON PHYSICS
(J C B Mohr (paul Siebeck), 2013-01-01)
Four-fermion operators have been utilized in the past to link the quark-exchange processes in the interaction of hadrons with the effective meson-exchange amplitudes. In this paper, we apply the similar idea of Fierz ...
Pressure of massless hot scalar theory in the boundary effective theory framework
(AMER PHYSICAL SOC, 2011)
We use the boundary effective theory approach to thermal field theory in order to calculate the pressure of a system of massless scalar fields with quartic interaction. The method naturally separates the infrared physics, ...
Supergraph approach in a higher-order linear delta expansion calculation of the effective potential for F-type broken supersymmetry
(Amer Physical Soc, 2012-10-11)
In this work, we adopt the simplest model that spontaneously breaks supersymmetry, namely, the minimal O'Raifeartaigh model. The effective potential is computed in the framework of the linear delta expansion approach up ...
