The production of a $${\text {Z}}$$ Z boson, decaying to two charged leptons, in association with jets in proton-proton collisions at a centre-of-mass energy of 13$$\,\text {TeV}$$ TeV is measured. Data recorded with the CMS detector at the LHC are used that correspond to an integrated luminosity of 2.19$$\,\text {fb}^\text {-1}$$ fb-1 . The cross section is measured as a function of the jet multiplicity...
A search for heavy narrow resonances decaying into four-lepton final states has been performed using proton–proton collision data at s=8TeV collected by the CMS experiment, corresponding to an integrated luminosity of 19.7fb−1. No excess of events over the standard model background expectation is observed. Upper limits for a benchmark model on the product of cross section and branching fraction for...
