Primordial black holes and magnetic fields in conformal neutrino mass models
Shyam Balaji, João Gonçalves, Danny Marfatia +2
Sufficiently strong and long-lasting first-order phase transitions can produce primordial black holes (PBHs) that contribute substantially to the dark matter abundance of the Unive…
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 Dark Gauge Sectors
Alexander Belyaev, Mårten Bertenstam, João Gonçalves +3
We explore gravitational-wave (GW) signatures from a strong first-order phase transition in a non-Abelian dark sector, which naturally gives rise to vector dark matter (DM). We con…
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…
Tridiagonal scalar mass matrix in the CP4 3HDM and its implications
Bei Liu, Igor P. Ivanov, João Gonçalves
When parametrizing multi-Higgs potentials, it is desirable to express its coefficients via observables. This is routinely done for the 2HDM, but this approach often fails in more e…
