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…

Decay of de Sitter vacua by thermal activation
Jaume Garriga, Ariel Megevand
Decay of a de Sitter vacuum may proceed through a "static" instanton, representing pair creation of critical bubbles separated by a distance comparable to the Hubble radius -- a pr…
