Uncovering Natural Supersymmetry via the interplay between the LHC and direct Dark Matter detection
journal contribution
posted on 2023-06-09, 07:24 authored by Daniele Barducci, Alexander Belyaev, Aoife K M Bharucha, Werner Porod, Veronica SanzWe have explored Natural Supersymmetry (NSUSY) scenarios with low values of the µ parameter which are characterised by higgsino-like Dark Matter (DM) and compressed spectra for the lightest MSSM particles, ?10, ?20 and ?1±. This scenario could be probed via monojet signatures, but as the signal-to-background ratio (S/B) is low we demonstrate that the 8 TeV LHC cannot obtain limits on the DM mass beyond those of LEP2. On the other hand, we have found, for the 13 TeV run of the LHC, that by optimising kinematical cuts we can bring the S/B ratio up to the 5(3)% level which would allow the exclusion of the DM mass up to 200(250) GeV respectively, significantly extending LEP2 limits. Moreover, we have found that LUX/XENON1T and LHC do play very complementary roles in exploring the parameter space of NSUSY, as the LHC has the capability to access regions where DM is quasi-degenerate with other higgsinos, which are challenging for direct detection experiments.
