Black hole accretion discs and screened scalar hair (2016)
Journal Article
Davis, A. C., Gregory, R., & Jha, R. (2016). Black hole accretion discs and screened scalar hair. Journal of Cosmology and Astroparticle Physics, 2016(10), Article 024. https://doi.org/10.1088/1475-7516/2016/10/024

We present a novel way to investigate scalar field profiles around black holes with an accretion disc for a range of models where the Compton wavelength of the scalar is large compared to other length scales. By analysing the problem in ``Weyl" coord... Read More about Black hole accretion discs and screened scalar hair.

Thermodynamics of Accelerating Black Holes (2016)
Journal Article
Appels, M., Gregory, R., & Kubizňák, D. (2016). Thermodynamics of Accelerating Black Holes. Physical Review Letters, 117(13), Article 131303. https://doi.org/10.1103/physrevlett.117.131303

We address a long-standing problem of describing the thermodynamics of a charged accelerating black hole. We derive a standard first law of black hole thermodynamics, with the usual identification of entropy proportional to the area of the event hori...

The fate of the Higgs vacuum (2016)
Journal Article
Burda, P., Gregory, R., & Moss, I. (2016). The fate of the Higgs vacuum. Journal of High Energy Physics, 2016(6), Article 25. https://doi.org/10.1007/jhep06%282016%29025

We have recently suggested that tiny black holes can act as nucleation seeds for the decay of the metastable Higgs vacuum. Previous results applied only to the nucleation of thin-wall bubbles, and covered a very small region of parameter space. This... Read More about The fate of the Higgs vacuum.

The Fate of the Higgs Vacuum (2016)
Presentation / Conference Contribution
Gregory, R., & Moss, I. (2016, December). The Fate of the Higgs Vacuum. Presented at 38th International Conference on High Energy Physics (ICHEP2016), Chicago, USA

This talk reviews our recent work showing how tiny black holes can act as nucleation sites for the decay of the metastable Higgs vacuum [1, 2, 3, 4]. We start by discussing the formation of thin wall bubbles of true vacuum inside a false vacuum, and... Read More about The Fate of the Higgs Vacuum.
