Resumen
The CMS experiment at the Large Hadron
Collider is one of the biggest and most complex scientific instruments of our
time, designed to elucidate the mechanism of electroweak symmetry breaking in
the Standard Model of particle physics. This mechanism provides mass to the
heavy gauge bosons and would result in a new particle: the Higgs boson. On July
4th the discovery of a new boson was announced in CERN by both the ATLAS and
CMS Collaboration. While at first sight this new boson is compatible with the
Standard Model Higgs boson, more tests have to be performed to confirm that
this new particle exhibits all properties assigned to the Higgs boson.
The decay of the new boson to four leptons is one of
the most powerful channels to study its spin and parity. The design and status
of the analysis will be presented. The results
are based on proton-proton collisions data corresponding to integrated
luminosities of up to at and at . The
analysis of the new data should confirm the observation of a new boson at a
mass near 125 GeV and the first measurements of the
boson properties will be shown. At the end of the talk a short overview of the
newest CMS Higgs results, presented at the Moriond 2013
conference will be discussed.
