Minimal supersymmetric left-right model
(Melfo, Alejandra; Aulakh, Charanjit S.; Senjanovic, Goran)
Abstract
We construct the truly minimal left-right symmetric model by utilizing only the fields dictated by ...
Massive gauge axion fields

Massive gauge axion fields
(Khoudeir, Adel; Arias, Pío José)
Abstract
A gauge invariant formulation for the massive axion is considered. The axion acquires mass through a topological term which couples a (pseudo)scalar ...
Massive vector Chern-Simons gravity
(SABER ULA, 2005-01-06)
Massive vector Chern-Simons gravity
(Khoudeir, Adel; Aragone, Carlos; Pío José, Arias)
Abstract
We present a second order gravity action which consists of ordinary Einstein action augmented by a first-order, ...
Massive triadic Chern-Simons spin-3 theory
(SABER ULA, 2005-01-06)
Massive triadic Chern-Simons spin-3 theory
(Khoudeir, Adel; Aragone, Carlos)
Abstract
We introduce the massive gauge invariant, second order pure spin-3 theory in three dimensions. It consists of the addition of ...
A note about localized photons on the brane
(SABER ULA, 2005-01-06)
A note about localized photons on the brane
(Khoudeir, Adel)
Abstract
A first order formulation for the Maxwell field in five dimensions is dimentionally reduced using the Randall-Sundrum mechanism. We will see ...
Supersymmetry and large-scale left-right symmetry
(SABER ULA, 2005-01-06)
Supersymmetry and large-scale left-right symmetry
(Melfo, Alejandra; Aulakh, Charanjit S.; Rasin, Andrija; Senjanovic, Goran)
Abstract
We show that the low energy limit of the minimal supersymmetric Left-Right models ...
Bubble collisions and defect formation in a damping environment
(SABER ULA, 2005-01-06)
Bubble collisions and defect formation in a damping environment
(Melfo, Alejandra; Ferrera, Antonio)
Abstract
Within the context of a first-order phase transition in the early Universe, we study the collision process ...
