Description
The CMS results are presented for an analysis of the mass, width, and spin-parity properties of a Higgs boson candidate near 126 GeV in the $ZZ\to 4l$ channel, with $l=\mu,e$. The analysis utilizes the full dataset recorded by CMS of 5.1 $\text{fb}^{-1}$ and 19.7 $\text{fb}^{-1}$ of LHC $pp$ collisions at a center-of-mass energy of $\sqrt{s} = 7$ and 8 TeV respectively. The mass is measured to be $125.6\pm 0.4 (\text{stat.})\pm 0.2(\text{syst.})$ GeV, and the total width $\le 3.4$ GeV at a 95% confidence level. The standard model scalar hypothesis is compared against twelve alternate spin-parity hypotheses. The spin-parity is found to be consistent with the standard model expectations.
