Dark matter spin characterization in mono-Z channels

Dark matter spin characterization in mono-Z channels
Dark matter spin characterization in mono-Z channels

The B-L supersymmetric Standard Model (BLSSM) is an ideal testing ground of the spin nature of dark matter (DM) as it offers amongst its candidates both a spin-1/2 (the lightest neutralino) and spin-0 (the lightest right-handed sneutrino) state. We show that the mono-Z channel can be used at the Large Hadron Collider (LHC) to diagnose whether a DM signal is characterized within the BLSSM by a fermionic or (pseudo)scalar DM particle. Sensitivity to either hypothesis can be obtained after only 100 fb-1 of luminosity following runs 2 and 3 of the LHC.

Abstract

The B-L supersymmetric Standard Model (BLSSM) is an ideal testing ground of the spin nature of dark matter (DM) as it offers amongst its candidates both a spin-1/2 (the lightest neutralino) and spin-0 (the lightest right-handed sneutrino) state. We show that the mono-Z channel can be used at the Large Hadron Collider (LHC) to diagnose whether a DM signal is characterized within the BLSSM by a fermionic or (pseudo)scalar DM particle. Sensitivity to either hypothesis can be obtained after only 100 fb-1 of luminosity following runs 2 and 3 of the LHC.
