Curvature-induced electroweak symmetry breaking and phase transition of a Higgs-portal dark scalar field
Andreas Mantziris
This overview of the study arXiv:2407.18845, regarding the possibility of generating gravitational waves from a curvature-induced phase transition of a non-minimally coupled scalar…
Inflationary dynamics of non-minimally coupled matter-curvature theories
Miguel Barroso Varela, Orfeu Bertolami, Andreas Mantziris
This study examines how inflationary dynamics are affected by theories with a non-minimal coupling between matter and curvature. Both positive and negative corrections to th…
Gravitational waves from a curvature-induced phase transition of a Higgs-portal dark matter sector
Andreas Mantziris, Orfeu Bertolami
The study of interactions between dark matter and the Higgs field opens an exciting connection between cosmology and particle physics, since such scenarios can impact the features…
From Hubble to Bubble
Maciej Kierkla, Giorgio Laverda, Marek Lewicki +4
The detection of a stochastic Gravitational Wave (GW) background sourced by a cosmological phase transition would allow us to see the early Universe from a completely new perspecti…
Higgs vacuum metastability in gravity
Andreas Mantziris
Experimental data suggest that the Higgs potential has a lower ground state at high field values. Consequently, decaying from the electroweak to the true vacuum nucleates bubbles t…
Ending inflation with a bang: Higgs vacuum decay in gravity
Andreas Mantziris
According to the current experimental data, the Higgs vacuum appears to be metastable due to the development of a second lower ground state in its potential. Consequently, vacuum d…
On the cosmological implications of the electroweak vacuum instability: constraining the non-minimal coupling with inflation
Andreas Mantziris
Our current measurements of the Standard Model parameters imply that the Higgs field resides in a metastable electroweak vacuum, where the vacuum can decay to a lower ground state,…
Cosmological implications of EW vacuum instability: constraints on the Higgs-curvature coupling from inflation
Andreas Mantziris
The current experimentally measured parameters of the Standard Model (SM) suggest that our Universe lies in a metastable electroweak vacuum, where the Higgs field is prone to vacuu…
Vacuum decay constraints on the Higgs curvature coupling from inflation
Andreas Mantziris, Tommi Markkanen, Arttu Rajantie
We derive lower bounds for the Higgs-curvature coupling from vacuum stability during inflation in three inflationary models: quadratic and quartic chaotic inflation, and Starobinsk…
Neutron star matter equation of state including -hexaquark degrees of freedom
A. Mantziris, A. Pastore, I. Vidaña +3
We present an extension of a previous work where, assuming a simple free bosonic gas supplemented with a relativistic meand field model to describe the pure nucleonic part of the E…
