A closer look at the explanation of the ATOMKI nuclear anomalies
P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim
We revisit the gauged explanation of the ATOMKI nuclear anomalies, in which the new gauge boson is the hypothetical particle. It is known that the vanilla $B-L…
Lepton Flavor Specific Extended Higgs Model
B. L. Gonçalves, Matthew Knauss, Marc Sher
In extended Higgs models, a discrete symmetry is needed in the quark sector to avoid tree-level flavor-changing neutral currents. However, this is not necessary the case in the lep…
The hidden side of scalar-triplet models with spontaneous CP violation
P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim
Scalar triplet extensions of the Standard Model provide an interesting playground for the explanation of neutrino mass suppression through the type-II seesaw mechanism. Propelled b…
in the 2HDM and slightly beyond -- an updated view
P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim +1
The recent measurement of the muon anomaly continues to defy a Standard Model explanation, but can be accommodated within the framework of two Higgs doublet models. If one…
Stability of neutral minima against charge breaking in the Higgs triplet model
P. M. Ferreira, B. L. Gonçalves
We analyse the possibility of charge breaking minima developing in the Higgs triplet model, and under what conditions they are deeper than charge-preserving ones. Analytical expres…
