1. Atomki Anomaly in Family-Dependent U(1) Extension of the Standard Model / Delle Rose, Luigi ; Khalil, Shaaban ; King, Simon J. D. ; Moretti, Stefano ; et al
In the context of a gauge invariant, nonanomalous, and family-dependent (nonuniversal) U(1) extension of the Standard Model, wherein a new high-scale mechanism generates masses and couplings for the first two fermion generations and the standard Higgs mechanism does so for the third one, we find solutions to the anomaly observed by the Atomki Collaboration in the decay of excited states of beryllium, in the form of a very light Z state, stemming from the U(1) symmetry breaking, with significant axial couplings so as to evade a variety of low-scale experimental constraints..

3. Light charged Higgs boson with dominant decay to quarks and its search at the LHC and future colliders / Akeroyd, A. G. ; Moretti, Stefano ; Song, Muyuan
The possibility of a light charged Higgs boson H± that decays predominantly to quarks (cs and/or cb) and with a mass in the range 80 GeVmH±90 GeV is studied in the context of three-Higgs-doublet models (3HDMs). [...]

In the next-to-minimal supersymmetric standard model (NMSSM), it is possible to have strong mass degeneracies between the new singletlike scalar and the heavy doubletlike scalar, as well as between the singletlike and doubletlike pseudoscalar Higgs states. [...]
