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…
Bound on four-dimensional Planck mass
Xavier Calmet, Marco Feliciangeli
In this note we derive a bound using data from cosmic rays physics on a model recently proposed to solve the hierarchy problem by lowering the Planck scale to the TeV region withou…
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…
Quantum gravity at a TeV and the renormalization of Newton's constant
Xavier Calmet, Stephen D. H. Hsu, David Reeb
We examine whether renormalization effects can cause Newton's constant to change dramatically with energy, perhaps even reducing the scale of quantum gravity to the TeV region with…
