Novel Multilepton Signatures from the Fermionic Portal to Vector Dark Matter
Alexander Belyaev, Manimala Chakraborti, Claire Shepherd-Themistocleous +1
We perform a collider study of a novel multilepton signature arising from pair production of heavy vector-like leptons followed by cascade decays through a dark sector. In the muon…

Soft-Dimuon Signature from Two-Component Scalar Dark Matter at the LHC
Alexander Belyaev, Manimala Chakraborti, Shu Chen +4
We explore the potential of the Large Hadron Collider to probe a two-component scalar dark matter scenario in the opposite-sign dimuon plus missing transverse energy final state, a…

Consistent Excesses in the LHC Electroweak SUSY Searches: GUT-based Singlino/Higgsino Interpretation in the NMSSM
Emanuele Bagnaschi, Manimala Chakraborti, Sven Heinemeyer +1
The search for supersymmetric models remains one of the main items on the BSM search program at the LHC, with EW SUSY partners still allowed with masses as low as a few hundred GeV…
