Axion Paradigm with Color-Mediated Neutrino Masses
A. Batra, H. B. Câmara, F. R. Joaquim +2
We propose a generalized Kim-Shifman-Vainshtein-Zakharov-type axion framework in which colored fermions and scalars act as two-loop Majorana neutrino-mass mediators. The global Pec…
Confronting the 95 GeV excesses within the UN2HDM
J. A. Aguilar-Saavedra, H. B. Câmara, F. R. Joaquim +1
We consider the small excesses around 95 GeV found in several searches for a new scalar in , and final states. Instead of trying to accommodate them all, as is…
Dark linear seesaw mechanism
A. Batra, H. B. Câmara, F. R. Joaquim
We propose a minimal model where a dark sector, odd under a discrete symmetry, is the seed of lepton number violation in the neutrino sector at the loop level, in t…
Hybrid scoto/seesaw: flavour and dark matter
D. M. Barreiros, H. B. Câmara, F. R. Joaquim
We propose a model based on the interplay between the type-II seesaw and scotogenic neutrino mass generation mechanisms. The setup features a discrete flavour symmet…
Dark-sector seeded solution to the strong CP problem
H. B. Câmara, F. R. Joaquim, J. W. F. Valle
We propose a novel realization of the Nelson-Barr mechanism "seeded'' by a dark sector containing scalars and vector-like quarks. Charge-parity (CP) and a symmetry…
