Observing Double Higgs Production at the LHC via Neutrino Feature Engineering in
Alexandre Alves, Eduardo da Silva Almeida, Diego S. V. Gonçalves
Double Higgs production is challenging even at the High Luminosity LHC. The Standard Model (SM) has a moderate cross section compared t…

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…

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…
