See-saw and supersymmetry or exact R-parity (Melfo, Alejandra; Aulakh, Charanjit S.; Rasin, Andrija; Senjanovic, Goran) Abstract We show how the renormalizable see-saw mechanism in the context of supersymmetry and ...

SO(10) theory of R-parity and neutrino mass (Melfo, Alejandra; Aulakh, Charanjit S.; Bajc, Borut; Rasin, Andrija; Senjanovic, Goran) Abstract We study the Higgs sector of a SO(10) grand unified theory which predicts ...

Symmetry nonrestoration at high temperature and the monopole problem (Melfo, Alejandra; Dvali, Gia; Senjanovic, Goran) Abstract We investigate the high temperature behavior of SU(5) in its minimal version. We show ...

Broken symmetries in the early universe (Melfo, Alejandra; Senjanovic, Goran) Abstract We give a brief review of recent results on symmetry nonrestoration at high temperature. The year is 1010 B.C. All the ...

Self-dual spin-3 and 4 theories (Khoudeir, Adel; Aragone, Carlos) Abstract We present self-dual spin-3 and 4 actions using relevant dreibein fields. Since these actions start with a Chern-Simons like kinetic term ...

Light-front dynamics of massive vector Chern-Simons gravity (Khoudeir, Adel; Aragone, Carlos; Arias, Pío José) Abstract We present a second order gravity action which consists of ordinary Einstein action augmented ...

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 ...

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 ...

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 ...

On supersymmetry at high temperature (Melfo, Alejandra; Bajc, Borut; Senjanovic, Goran) Abstract While it is possible to find examples of field theories with a spontaneously broken symmetry at high temperature, in ...
