Exploring mixed lepton-quark interactions in non-resonant leptoquark production at the LHC
João Gonçalves, António P. Morais, António Onofre +1
Searches for new physics (NP) at particle colliders typically involve multivariate analysis of kinematic distributions of final state particles produced in a decay of a hypothetica…
Exploring the viability of pseudo Nambu-Goldstone boson as ultralight dark matter in a mass range relevant for strong gravity applications
António P. Morais, Vinícius Oliveira, António Onofre +2
We study a simple extension of the Standard Model featuring a dark sector with an ultralight pseudo Nambu-Goldstone boson as dark matter candidate. We focus on the mass range $\mat…
Gravitational echoes of lepton number symmetry breaking with light and ultralight Majorons
Andrea Addazi, Antonino Marcianò, António P. Morais +3
We formulate a version of the low-scale Majoron model equipped with an inverse seesaw mechanism featuring lepton-number preserving dimension-6 operators in the scalar potential. Co…
Gravitational waves from a scotogenic two-loop neutrino mass model
Cesar Bonilla, A. E. Cárcamo Hernández, João Gonçalves +3
We propose a framework to account for neutrino masses at the two-loop level. This mechanism introduces new scalars and Majorana fermions to the Standard Model. It is assumed the ex…
