Connecting the Higgs Potential and Primordial Black Holes
De-Chang Dai, Ruth Gregory, Dejan Stojkovic
It was recently demonstrated that small small black holes can act as seeds for nucleating decay of the metastable Higgs vacuum, dramatically increasing the tunneling probability. A…
Higgs Cosmology and Dark Matter
Ian G. Moss, Ruth Gregory
Higgs vacuum stability has important consequences for cosmology. In particular, we argue that if the Higgs vacuum is metastable, then the dark matter cannot contain a single black…
Gravitational Effects in g Factor Measurements and High-Precision Spectroscopy: Limits of Einstein's Equivalence Principle
Ulrich D. Jentschura
We study the interplay of general relativity, the equivalence principle, and high-precision experiments involving atomic transitions and g factor measurements. In particular, we de…
Effective action and motion of a cosmic string
Malcolm Anderson, Filipe Bonjour, Ruth Gregory +1
We examine the leading order corrections to the Nambu effective action for the motion of a cosmic string, which appear at fourth order in the ratio of the width to radius of curvat…
A Note on the Finiteness of Curvature at Cosmic String Cusps
Ruth Gregory
We examine a Nambu-Goto string trajectory in the neighbourhood of a cusp and determine the extrinsic curvature invariants. These are demonstrated to be finite, in contradiction wit…
