Bounds on the Nonminimal Coupling of the Higgs Boson to Gravity
Michael Atkins, Xavier Calmet
We derive the first bound on the value of the Higgs boson non-minimal coupling to the Ricci scalar. We show that the recent discovery of the Higgs boson at the Large Hadron Collide…
Brane World Models Need Low String Scale
Ignatios Antoniadis, Michael Atkins, Xavier Calmet
Models with large extra dimensions offer the possibility of the Planck scale being of order the electroweak scale, thus alleviating the gauge hierarchy problem. We show that these…
Remarks on Higgs Inflation
Michael Atkins, Xavier Calmet
We discuss models where the Higgs boson of the electroweak standard model plays the role of the inflaton. We focus on the question of the violation of perturbative unitarity due to…
Unitarity bounds on low scale quantum gravity
Michael Atkins, Xavier Calmet
We study the unitarity of models with low scale quantum gravity both in four dimensions and in models with a large extra-dimensional volume. We find that models with low scale quan…
Suppressing Lepton Flavour Violation in a Soft-Wall Extra Dimension
Michael Atkins, Stephan J. Huber
A soft-wall warped extra dimension allows one to relax the tight constraints imposed by electroweak data in conventional Randall-Sundrum models. We investigate a setup, where the l…
