Constraining the Inert Doublet Model using Vector Boson Fusion

The European physical journal / C 79(11), 924 (2019). doi:10.1140/epjc/s10052-019-7436-6
In this work, we use a recast of the Run II search for invisible Higgs decays within Vector Boson Fusion to constrain the parameter space of the Inert Doublet model, a two Higgs doublet model with a dark matter candidate. When including all known theoretical as well as collider constraints, we find that the above can rule out a relatively large part in the $m_H,\,\lambda _{345}$ parameter space, for dark scalar masses $m_H\,\le \,100\,{\mathrm{GeV}}$. Including the latest dark matter constraints, a smaller part of parameter space remains which is solely excluded from the above analysis. We also discuss the sensitivity of monojet searches and multilepton final states from Run II.
