Free energy of Lorentz-violating QED at high temperature
(AMER PHYSICAL SOC, 2010)
In this paper we study the one-and two-loop contribution to the free energy in QED with Lorentz symmetry breaking introduced via constant CPT-even Lorentz-breaking parameters at the high temperature limit. We find the ...
Aetherlike Lorentz-breaking actions
(AMER PHYSICAL SOC, 2010)
We show that CPT-even aetherlike Lorentz-breaking actions, for the scalar and electromagnetic fields, are generated via their appropriate Lorentz-breaking coupling to spinor fields, in three, four, and five space-time ...
Higher-derivative supersymmetric gauge theory
(AMER PHYSICAL SOC, 2011)
We study the one-loop low-energy effective action for the higher-derivative superfield gauge theory coupled to chiral matter.
On the effective potential in higher-derivatives superfield theories
(ELSEVIER SCIENCE BV, 2009)
we study the one-loop quantum corrections for higher-derivative superfield theories, generalizing the approach for calculating the superfield effective potential. In particular, we calculate the effective potential for two ...
On the superfield effective potential in three dimensions
(ELSEVIER SCIENCE BV, 2009)
We develop the superfield approach to the effective potential in three dimensions and calculate the one-loop and two-loop Kahlerian effective potential in commutative and noncommutative cases. (C) 2009 Published by Elsevier B.V.
On duality of the noncommutative supersymmetric Maxwell-Chern-Simons theory
(ELSEVIER SCIENCE BV, 2008)
We study the possibility of establishing the dual equivalence between the noncommutative supersymmetric Maxwell-Chern-Simons theory and the noncommutative supersymmetric self-dual theory. It turns to be that whereas in the ...
Effective potential for Horava-Lifshitz-like theories
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
We study the one-loop effective potential for some Horava-Lifshitz-like theories.
All-loop finiteness of the two-dimensional noncommutative supersymmetric gauge theory
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETYMULHOUSE, 2012)
Within the superfield approach, we discuss the two-dimensional noncommutative super-QED. Its all-order finiteness is explicitly shown. Copyright (C) EPLA, 2012
Finiteness of the noncommutative supersymmetric Maxwell-Chern-Simons theory
(AMER PHYSICAL SOC, 2008)
Within the superfield approach, we prove the absence of UV/IR mixing in the three-dimensional noncommutative supersymmetric Maxwell-Chern-Simons theory at any loop order and demonstrate its finiteness in one, three, and ...
Perturbative finiteness of three-dimensional supersymmetric QED to all orders
(AMER PHYSICAL SOC, 2008)
Within the superfield formalism, we study the ultraviolet properties of the three-dimensional super-symmetric quantum electrodynamics. The theory is shown to be finite at all loop orders in a particular gauge.
