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…
Leptogenesis and Primordial Magnetic Fields
Andrew J. Long, Eray Sabancilar, Tanmay Vachaspati
The anomalous conversion of leptons into baryons during leptogenesis is shown to produce a right-handed helical magnetic field; in contrast, the magnetic field produced during elec…
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…
