Sumario: | These proceedings summarize the ATLAS and CMS collaboration measurement of Higgs prop- erties. The properties discussed include mass, spin, parity and the coupling of the Higgs candidate to vector bosons. The combined measurement of the mass as measured by the ex- periments combined is mH = 125. 09 +/- 0.21 (statistical uncertainty) +/- 0.11 (scale uncertainty) +/- 0.02 (other uncertainty) +/- 0.01 (theoretical uncertainty) GeV. Both collaboration observe that the data are consistent with a Standard Model Higgs boson of spin/parity JP = 0+. Alternative spin-1 and spin-2 hypotheses are excluded by both collaborations at a greater than 99.9% con dence level. Within the spin-0 hypothesis the coupling of the Higgs particle to vector gauge bosons is also investigated. |
