Gravitational waves from a scotogenic two-loop neutrino mass model
Bonilla, Cesar; Hernández, A. E. Cárcamo; Pino, João Pedro; N., Vishnudath K.; Morais, António P.; Pasechnik, R.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 assumes the existence of a global U(1)×Z2 symmetry which after partial breaking provides the stability of the dark matter candidates of the theory. The rich structure of the potential allows for the possibility of first-order phase transitions (FOPTs)...

Abazov, V. M.; Abbott, B.; Acharya, B. S.; Adams, M.; Adams, T.; Agnew, J. P.; Alexeev, G. D.; Alkhazov, G.; Alton, A.; Alves, G. A.; Antchev, G.Made available in DSpace on 2022-04-28T19:42:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-08-06; We describe an analysis comparing the pp¯ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated ...
Collider signatures of vector-like fermions from a flavor symmetric model
Bonilla, Cesar; Cárcamo Hernández, A. E.; Gonçalves, João; Freitas, Felipe F.; Morais, António P.; Pasechnik, R.We propose a model with two Higgs doublets and several $SU(2)$ scalar singlets with a global non-Abelian flavor symmetry $\mathcal{Q}_6\times\mathcal{Z}_2$. This discrete group accounts for the observed pattern of fermion masses and mixing angles after spontaneous symmetry breaking. In this scenario only the third generation of fermions get their masses as in the Standard Model (SM). The masses of the remaining...

Reviving trinification models through an E6-extended supersymmetric GUT
Morais, A. P.; Pasechnik, R.; Wessén, J.; Ordell, A.; Sampaio, M.; Camrgo-Molina, J. E.We present a supersymmetric (SUSY) model based on trinification [SU(3)]^3 and family SU(3)_F symmetries embedded into a maximal subgroup of E8, where the sectors of light Higgs bosons and leptons are unified into a single chiral supermultiplet. The common origin of gauge trinification and of the family symmetry from E8 separates the model from other trinification-based GUTs, as it protects, in particular, the S...
