Augury of Darkness: The Low-Mass Dark Z' Portal
Alexandre Alves, Giorgio Arcadi, Yann Mambrini +2
Dirac fermion dark matter models with heavy mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to…
R-parity as a residual gauge symmetry : probing a theory of cosmological dark matter
Alexandre Alves, Giorgio Arcadi, P. V. Dong +3
We present a non-supersymmetric scenario in which the R-parity symmetry arises as a result of spontaneous gauge symmetry breaking, leading to a viable Dira…
Evading Direct Dark Matter Detection in Higgs Portal Models
Giorgio Arcadi, Christian Gross, Oleg Lebedev +2
Many models of Higgs portal Dark Matter (DM) find themselves under pressure from increasingly tight direct detection constraints. In the framework of gauge field DM, we study how s…
Dark Matter Phenomenology of SM and Enlarged Higgs Sectors Extended with Vector Like Leptons
Andrei Angelescu, Giorgio Arcadi
We will investigate the scenario in which the Standard Model (SM) Higgs sector and its 2-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the int…
Multicomponent Dark Matter from Gauge Symmetry
Giorgio Arcadi, Christian Gross, Oleg Lebedev +3
The composition of Dark Matter (DM) remains an important open question. The current data do not distinguish between single- and multi-component DM, while in theory constructions it…
Scrutinizing a di-photon resonance at the LHC through Moscow zero
Giorgio Arcadi, Pradipta Ghosh, Yann Mambrini +1
The ATLAS and CMS collaborations have recently released their new analyses of the diphoton searches. We look in detail the consequences of their results deriving strong constraints…
