Imprints of a Second Order Electroweak Phase Transition on the Stochastic Gravitational Wave Background
V. K. Oikonomou
In this work we shall study the impact of a second order electroweak phase transition occurring at GeV on the energy spectrum of the stochastic gravitational background…

Topological Electroweak Phase Transition
V. K. Oikonomou
In this work we shall consider the effects of a non-trivial topology on the effective potential of the Standard Model. Specifically we shall assume that the spacetime topology is $…

Theoretical Probes of Higgs-Axion non-perturbative Couplings
V. K. Oikonomou
In this work we investigate the phenomenological implications of several non-trivial axion-Higgs couplings, which cover most of the possible non-perturbative scenarios. Specificall…
