The total decay width of the Higgs boson has not yet been constrained precisely with the LHC data. Some of the width could be associated to decays to invisible particles, for example Dark Matter particles. A search for invisible decays of the Higgs boson is performed using about 10 fb-1 of p-p collisions at 13 TeV.
Several theories beyond the Standard Model, like the 2HDM, predict the existence of high mass charged Higgs particles. Such charged Higgses, produced in association with a top quark, are searched for in the tau + jets decay channel and in the top-bottom decay channel, using about 10 fb-1 of p-p collisions at 13 TeV.
