Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at √s=13 TeV
A search for a new scalar resonance decaying to a pair of Z bosons is performed in the mass range from 130 GeV to 3 TeV, and for various width scenarios. The analysis is based on proton-proton collisions recorded by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity...

| description | A search for a new scalar resonance decaying to a pair of Z bosons is performed
in the mass range from 130 GeV to 3 TeV, and for various width scenarios. The analysis
is based on proton-proton collisions recorded by the CMS experiment at the LHC in 2016,
corresponding to an integrated luminosity of 35.9 fb−1 at a center-of-mass energy of 13 TeV.
The Z boson pair decays are reconstructed using the 4`, 2`2q, and 2`2ν final states, where
` = e or µ. Both gluon fusion and electroweak production of the scalar resonance are
considered, with a free parameter describing their relative cross sections. A dedicated
categorization of events, based on the kinematic properties of associated jets, and matrix
element techniques are employed for an optimal signal and background separation. A
description of the interference between signal and background amplitudes for a resonance
of an arbitrary width is included. No significant excess of events with respect to the
standard model expectation is observed and limits are set on the product of the cross
section for a new scalar boson and the branching fraction for its decay to ZZ for a large
range of masses and widths |
