AbstractIn 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 $$m_H,\,\lambda _{345}$$mH,λ345 parameter space, for dark scalar masses $$m_H\,\le \,100\,{\mathrm{GeV}}$$mH≤100GeV. 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.

We study the lepton-flavor-violating processes of τ- → μ-PP decays with PP = K+K-, [Formula: see text], π+π-, π0π0 in the framework of two-Higgs-doublet model III by virtue of the chiral perturbation theory. In this model, only three neutral Higgs bosons contribute to these decays. With the current experimental constraints, we show that (a) the contributions of the |λuu(dd)| term are very small for these four decays; (b) we get the correlation between |λss| and |λτμ|; for |λτμ| ~ 10–400, one has |λss| ~ 40–1; (c) in the existing model parameter space, Br (τ- → μ- K+K-) could reach the order of [Formula: see text], but Br (τ → μ-π+π-/π0π0) are too small to be observed.
