/Higgs inflation and the hierarchy problem
Pedro G. Ferreira, Christopher T. Hill, Johannes Noller +1
We analyse Starobinsky inflation in the presence of the Brout Englert Higgs (BEH) boson with a non-minimal coupling to the Ricci scalar, . The latter induces a coupling of the m…
Starobinksy Inflation, Gravitational Contact Terms and the Induced BEH Boson Mass
Christopher T. Hill, Graham G. Ross
The Starobinsky model of inflation remains consistent with observation, forty years after its introduction. It provides a well motivated origin for the scalar inflaton, the "scaler…
Gravitational Contact Interactions and the Physical Equivalence of Weyl Transformations in Effective Field Theory
Christopher T. Hill, Graham G. Ross
Theories of scalars and gravity, with non-minimal interactions, , have graviton exchange induced contact terms. These terms arise in single particle red…
Scale independent inflation
Pedro G. Ferreira, Christopher T. Hill, Johannes Noller +1
Weyl (scale) invariant theories of scalars and gravity can generate all mass scales spontaneously. In this paper we study a particularly simple version -- scale invariant gra…
A new approach to gauge coupling unification and proton decay
Stefan Pokorski, Krzysztof Rolbiecki, Graham G. Ross +1
An analytical formalism, including RG running at two loop order, is used to link the supersymmetric and GUT spectra in any GUT model in which the three gauge couplings unify. In ea…
Inflation in a scale invariant universe
Pedro G. Ferreira, Christopher T. Hill, Johannes Noller +1
A scale-invariant universe can have a period of accelerated expansion at early times: inflation. We use a frame-invariant approach to calculate inflationary observables in a scale…
