Measurements of Higgs Boson Properties at the LHC.

The properties of the Higgs boson candidate, whose discovery was announced in July 2012 by ATLAS and CMS collaborations, have been measured by using data collected by ATLAS and CMS experiment from pp collisions at the LHC at the center-of-mass energy of 7 TeV in 2011 and 8 TeV in 2012.The recents results concerning the measurement of the Higgs boson mass, the spin-parity are reported both from ATLAS and CMS. The first direct and the indirect constraints on the total Higgs width from CMS are extensively described.
