Measurements of Higgs boson production and properties in the ZZ decay channel using the CMS detector / Regnard, Simon Jean (Ecole Polytechnique) /CMS Collaboration
Measurements of Higgs boson properties using the Hâ??ZZâ??4l (l = e, μ) decay channel are presented, based on a data sample corresponding to an integrated luminosity of 12.9 fbâ??1 of pp collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC during 2016. The observed significance for the standard model Higgs boson is 6.2Ï? at a mass of mH = 125.09 GeV, where the expected significance is 6.5Ï?. [...]

A Simple Method to detect spontaneous CP Violation in multi-Higgs models / Ogreid, O.M. (Bergen Coll. Higher Educ.) ; Osland, P. (Bergen U.) ; Rebelo, M.N. (Lisbon, CFTP ; CERN)
For models with several Higgs doublets we present an alternative method to the one proposed by Branco, Gerard and Grimus, in 1984, to check whether or not CP is spontaneously violated in the Higgs potential. [...]

Dimension-6 Operator Analysis of the CLIC Sensitivity to New Physics / Ellis, John (King's Coll. London ; CERN) ; Roloff, Philipp (CERN) ; Sanz, Veronica (Sussex U.) ; You, Tevong (Cambridge U.)
We estimate the possible accuracies of measurements at the proposed CLIC $e^+e^-$ collider of Higgs and $W^+W^-$ production at centre-of-mass energies up to 3TeV, incorporating also Higgsstrahlung projections at higher energies that had not been considered previously, and use them to explore the prospective CLIC sensitivities to decoupled new physics.
