One-loop pseudoscalar mass in a 2HDM with a symmetry
P. M. Ferreira, Tomás F. Pinto
A two-Higgs doublet model with a discrete symmetry acquires, in its scalar and gauge sectors, an accidental continuous symmetry. One therefore finds, after spontaneous…

RG-stable parameter relations of a scalar field theory in absence of a symmetry
Howard E. Haber, P. M. Ferreira
The stability of tree-level relations among the parameters of a quantum field theory with respect to renormalization group (RG) running is typically explained by the existence of a…

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…
