Quasinormal frequencies in Reissner-Nordström de Sitter black holes: constraints from space-time and scalar field parameters
Anna Chrysostomou, Alan S. Cornell, Aldo Deandrea +1
We examine the quasinormal modes exhibited by a massive scalar test field carrying an electric charge, oscillating in the outer region of a Reissner-Nordström de Sitter black hole.…

Are there minimal exceptional aGUTs from stable 5D orbifolds?
Giacomo Cacciapaglia, Alan S. Cornell, Aldo Deandrea +4
In analysing five dimensional orbifolds with exceptional gauge groups, we seek to find stable vacua configurations which satisfy the minimal requirements for asymptotic grand unifi…

General vacuum stability of orbifold gauge breaking and application to asymptotic grand unification
Giacomo Cacciapaglia, Alan S. Cornell, Aldo Deandrea +4
We examine the vacuum stability of gauge symmetry breaking in five dimensions, compactified on the orbifold. We consider , ,…
