Dark Strings and their Couplings to the Standard Model
Jeffrey M. Hyde, Andrew J. Long, Tanmay Vachaspati
We consider the Standard Model extended by a hidden sector U(1)_X symmetry that is spontaneously broken at the TeV scale by the vacuum expectation value of an additional scalar fie…
Metastability of the False Vacuum in a Higgs-Seesaw Model of Dark Energy
Lawrence M. Krauss, Andrew J. Long
In a recently proposed Higgs-Seesaw model the observed scale of dark energy results from a metastable false vacuum energy associated with mixing of the standard model Higgs particl…
Gravitino Leptogenesis
Lawrence M. Krauss, Andrew J. Long, Subir Sabharwal
We explore here a new mechanism by which the out of equilibrium decay of heavy gravitinos, followed by possible R-parity violating decays in the Minimal Supersymmetric Standard Mod…
The Lee-Wick Standard Model at Finite Temperature
Richard F. Lebed, Andrew J. Long, Russell H. TerBeek
The Lee-Wick Standard Model at temperatures near electroweak scale is considered, with the aim of studying the electroweak phase transition. While Lee-Wick theories possess states…
