Does the BICEP2 Observation of Cosmological Tensor Modes Imply an Era of Nearly Planckian Energy Densities?
Chiu Man Ho, Stephen D. H. Hsu
BICEP2 observations, interpreted most simply, suggest an era of inflation with energy densities of order (, not far below the Planck density. However, model…
Grand unification through gravitational effects
Xavier Calmet, Stephen D. H. Hsu, David Reeb
We systematically study the unification of gauge couplings in the presence of (one or more) effective dimension-5 operators cHGG/4MPl, induced into the grand unified theory by grav…
Invisible Higgs boson, continuous mass fields and unHiggs mechanism
X. Calmet, N. G. Deshpande, X. G. He +1
We explore the consequences of an electroweak symmetry breaking sector which exhibits approximately scale invariant dynamics -- i.e., nontrivial fixed point behavior, as in unparti…
Quantum Gravitational Effects and Grand Unification
Xavier Calmet, Stephen D. H. Hsu, David Reeb
In grand unified theories with large numbers of fields, renormalization effects significantly modify the scale at which quantum gravity becomes strong. This in turn can modify the…
Colorful quantum black holes at the LHC
Xavier Calmet, Wei Gong, Stephen D. H. Hsu
We examine the LHC phenomenology of quantum black holes in models of TeV gravity. By quantum black holes we mean black holes of the smallest masses and entropies, far from the semi…
Grand unification and enhanced quantum gravitational effects
Xavier Calmet, Stephen D. H. Hsu, David Reeb
In grand unified theories with large numbers of fields, renormalization effects significantly modify the scale at which quantum gravity becomes strong. This in turn can modify the…
