Detonations and deflagrations in cosmological phase transitions
Ariel Megevand, Alejandro D. Sanchez
We study the steady state motion of bubble walls in cosmological phase transitions. Taking into account the boundary and continuity conditions for the fluid variables, we calculate…
Supercooling and phase coexistence in cosmological phase transitions
Ariel Megevand, Alejandro D. Sanchez
Cosmological phase transitions are predicted by Particle Physics models, and have a variety of important cosmological consequences, which depend strongly on the dynamics of the tra…
Electroweak Baryogenesis and New TeV Fermions
Marcela Carena, Ariel Megevand, Mariano Quiros +1
New fermions, strongly coupled to the Standard Model Higgs boson provide a well motivated extension of the Standard Model (SM). In this work we show that, once new physics at heavi…
Generation of baryon inhomogeneities in the electroweak phase transition
Ariel Megevand, Francisco Astorga
It is known that baryon number inhomogeneities may arise as a consequence of electroweak baryogenesis. Their geometry, size, and amplitude depend on the parameters that characteriz…
