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 ...

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 ...

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 ...

Formation of vortices in first order phase transitions (Melfo, Alejandra; Perivolaropoulos, Leandros) Abstract Using a toy model Lagrangian we investigate the formation of vortices in first order phase transitions. ...

Intermediate scales in supersymmetric GUTs: The survival of the fittest (Melfo, Alejandra; Aulakh, Charanjit S.; Bajc, Borut; Rasin, Andrija; Senjanovic, Goran) Abstract We show that intermediate scales in ...
