Exploring Top-Quark Signatures of Heavy Flavor-Violating Scalars at the LHC with Parametrized Neural Networks
Alexandre Alves, Eduardo da Silva Almeida, Alex G. Dias +1
In this work, we study flavor-violating scalars (flavons) in a range of large masses that have not been explored previously. We model the interactions with an effective field theor…
Fractionary Charged Particles Confronting Lepton Flavor Violation and the Muon's Anomalous Magnetic Moment
Elmer Ramirez Barreto, Alex G. Dias
In light of the recent result published by the Fermilab Muon experiment, we investigate a simple model that includes particles of fractional electric charges: a colour-sing…
Same-Sign Taus Signatures of Maximally Flavor-Violating Scalars at the LHC
Alexandre Alves, Alex G. Dias, Eduardo da Silva Almeida +1
We explore single and double flavor-violating scalar (flavon) production at the 13 and 14 TeV LHC in an effective field theory formulation where flavons always change the flavor of…
Axion-Photon Interaction from Nonminimal Dimension-5 Lorentz-Violating Operators
A. J. G. Carvalho, A. G. Dias, A. F. Ferrari +3
In this paper, we discuss various possible schemes for the perturbative generation of the axion-photon interaction term in different Lorentz-breaking extensions of QED, involving o…
Scale-invariant 3-3-1-1 model with symmetry
Alex G. Dias, Julio Leite, B. L. Sánchez-Vega
Motivated by a possible interplay between the mechanism of dynamical symmetry breaking and the seesaw mechanism for generating fermion masses, we present a scale-invariant model th…
Axion-Neutrino Interplay in a Gauged Two-Higgs-Doublet Model
Alex G. Dias, Julio Leite, Diego S. V. Gonçalves
We propose a gauged two-Higgs-doublet model (2HDM) featuring an anomalous Peccei-Quinn symmetry, . Dangerous tree-level flavour-changing neutral currents, common in 2HDM…
