| Özet |
| The properties of a Higgs boson candidate are measured in the decay channel, with , , using data from collisions corresponding to an integrated luminosity of at the center-of-mass energy of and at , recorded with the CMS detector at the LHC. The new boson is observed as a narrow resonance with a local significance of 6.8 standard deviations, a measured mass of , and a total width at the 95% confidence level. The production cross section of the new boson times its branching fraction to four leptons is measured to be times that predicted by the standard model. Its spin-parity properties are found to be consistent with the expectations for the standard-model Higgs boson. The hypotheses of a pseudoscalar and all tested spin-1 boson hypotheses are excluded at the 99% confidence level or higher. All … |
