Atomki Anomaly in FamilyDependent $U(1{)}^{\prime}$ 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 familydependent (nonuniversal) $U(1{)}^{\prime}$ extension of the Standard Model, wherein a new highscale 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 ${Z}^{\prime}$ state, stemming from the $U(1{)}^{\prime}$ symmetry breaking, with significant axial couplings so as to evade a variety of lowscale experimental constraints..

Quantum interference among heavy NMSSM Higgs bosons
/ Das, Biswaranjan ; Moretti, Stefano ; Munir, Shoaib ; Poulose, Poulose
In the nexttominimal 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. [...]

Single production of vectorlike quarks with large width at the Large Hadron Collider
/ Carvalho, Alexandra ; Moretti, Stefano ; O’Brien, Dermot ; Panizzi, Luca ; et al
Vectorlike quarks (VLQs) are predicted by several theoretical scenarios of new physics and having colour quantum numbers they can copiously be produced at the Large Hadron Collider (LHC) so long that their mass is within the testable kinematic regime of this machine. [...]
