Measurement of other Higgs boson properties

The recent measurement of Higgs boson properties, cross section, spin-parity and non-standard model coupling (Lepton flavor violation, flavor changing neutral current), in the ATLAS and CMS experiments are reported. The total cross section is $33.0\pm5.3(stat.)\pm1.6(sys.)$pb, that is agreement with...

description The recent measurement of Higgs boson properties, cross section, spin-parity and non-standard model coupling (Lepton flavor violation, flavor changing neutral current), in the ATLAS and CMS experiments are reported. The total cross section is $33.0\pm5.3(stat.)\pm1.6(sys.)$pb, that is agreement with state-of-art theory predictions. The differential cross sections of several variables are also fair agreement with theory predictions. Various hypothesis tests for spin $1^{\pm}$ and $2^{\pm}$ scenarios has been performed. No indication favors spin 1 or 2 models has been observed. CP-mixing scenarios for spin 0 have been investigated. No significant deviation from the Standard Model $0^{+}$ has been observed. We also searched for anomalous couplings, the lepton flavor violating decay in $H\rightarrow \mu\tau$ events and flavor changing neutral current in $t\rightarrow qH$ events. No significant excess has been observed in LHC Run-I data.
