Abstract We perform a model-independent search for leptoquarks (LQs) at the Large Hadron Collider through their pair-production and subsequent decay into t t ¯ ττ $$ t\overline{t}\tau \tau $$ intermediate states. We show that, assuming full lumino

Abstract The workshop “Shedding light on X17” brings together scientists looking for the existence of a possible new light particle, often referred to as X17. This hypothetical particle can explain the resonant structure observed at $$\sim $$ ∼

Abstract Within the Exceptional Supersymmetric Standard Model (E $$_6$$ 6 SSM), we investigate signatures at the Large Hadron Collider (LHC) for a long-lived charged inert higgsino, which is degenerate with the inert neutralino at tree level and a sm

In the context of the B−L Supersymmetric Standard Model (BLSSM), we investigate the consistency of a scenario with a light Higgs boson with mass in the range 94−98 GeV and a Standard Model (SM) Higgs state at 125 GeV with the results of a search

In the simplest left-right extension of the Standard Model of particle interactions with one scalar bidoublet and one SU(2)R triplet for seesaw Majorana neutrino masses, the addition of a variety of fermion and scalar multiplets automatically makes t

We explore the Higgs mass spectrum in a class of Two Higgs Doublet Models (THDMs) in which a scalar SU(2)L doublet interacts only with quarks, while the second one interacts only with leptons. The spectrum includes two CP-even Higgs bosons, either of

We explain anomalies currently present in various data samples used for the measurement of the anomalous magnetic moment of electron (ae) and muon (aμ) in terms of an Aligned 2-Higgs Doublet Model with right-handed neutrinos. The explanation is driv

Abstract In the framework of the (B − L) Supersymmetric Standard Model (BLSSM), we assess the ability of ground and space based experiments to establish the nature of its prevalent Dark Matter (DM) candidate, the sneutrino, which could either be CP

Motivated by the tension between the Higgs mass and muon g−2 in minimal supersymmetric standard model (MSSM), we analyze the muon g−2 in supersymmetric B−L extension of the standard model (BLSSM) with inverse seesaw mechanism. In this model, th
