Criticality in the scale invariant standard model (squared)
Robert Foot, Archil Kobakhidze, Alexander Spencer-Smith
We consider first the standard model Lagrangian with Higgs potential term set to zero. We point out that this clasically scale invariant theory potentially exhibits radiati…
Origin of the Phonon Hall Effect in Rare-Earth Garnets
M. Mori, A. Spencer-Smith, O. P. Sushkov +1
The phonon Hall effect has been observed in the paramagnetic insulator, Tb3Gd5O12. A magnetic field applied perpendicularly to a heat current induces a temperature gradient that is…
Higgs Vacuum Stability in a Mass-Dependent Renormalisation Scheme
Alexander Spencer-Smith
Using a physical renormalisation scheme we derive mass-dependent renormalisation group equations for the running of the Higgs quartic coupling within the Standard Model. Subsequent…
The Higgs vacuum is unstable
Archil Kobakhidze, Alexander Spencer-Smith
So far, the experiments at the Large Hadron Collider (LHC) have shown no sign of new physics beyond the Standard Model. Assuming the Standard Model is correct at presently availabl…
Neutrino Masses and Higgs Vacuum Stability
Archil Kobakhidze, Alexander Spencer-Smith
The Standard Model electroweak vacuum has been found to be metastable, with the true stable vacuum given by a large, phenomenologically unacceptable vacuum expectation value $\appr…
Electroweak Vacuum (In)Stability in an Inflationary Universe
Archil Kobakhidze, Alexander Spencer-Smith
Recent analysis shows that if the 125-126 GeV LHC resonance turns out to be the Standard Model Higgs boson, the electroweak vacuum would be a metastable state at 98% C.L. In this p…
Bound states of spin-half particles in a static gravitational field close to the black hole field
A. F. Spencer-Smith, G. H. Gossel, J. C. Berengut +1
We consider the bound-state energy levels of a spin-1/2 fermion in the gravitational field of a near-black hole object. In the limit that the metric of the body becomes singular, a…
