Gravitational waves from color restoration in a leptoquark model of radiative neutrino masses
Mårten Bertenstam, Marco Finetti, António P. Morais +2
We study the first-order phase transitions and the emerging stochastic gravitational wave spectrum in a minimal leptoquark extension of the Standard Model that explains active neut…
Supercooled phase transitions in conformal dark sectors explain NANOGrav data
João Gonçalves, Danny Marfatia, António P. Morais +1
According to recent lore, it is difficult to explain the evidence for a stochastic gravitational wave background obtained by pulsar timing arrays with supercooled first-order phase…
Gravitational waves from supercooled phase transitions in conformal Majoron models of neutrino mass
João Gonçalves, Danny Marfatia, António P. Morais +1
We study supercooled first-order phase transitions above the QCD scale in a wide class of conformal Majoron-like U(1)' models that explain the totality of active neutrino oscillati…
Invisible Higgs decay from dark matter freeze-in at stronger coupling
Oleg Lebedev, António P. Morais, Vinícius Oliveira +1
We study the Higgs boson decay into dark matter (DM) in the framework of freeze-in at stronger coupling. Even though the Higgs-DM coupling is significant, up to order one, DM does…
Gravitational-Wave Signatures of Chiral-Symmetric Technicolor
Hao Yang, Felipe F. Freitas, Antonino Marciano +3
A chiral-symmetric technicolor model successfully reconciles the tension between electroweak precision tests and traditional technicolor models. Focusing on its simplest realizatio…
Gauge couplings evolution from the Standard Model, through Pati-Salam theory, into unification of families and forces
Francisco J. de Anda, Alfredo Aranda, António P. Morais +1
We explore the potential of ultimate unification of the Standard Model matter and gauge sectors into a single superfield in ten dimensions via an intermediate Pati-Salam gaug…
