Search for a narrow, spin-2 resonance decaying to a pair of Z bosons in the q q-bar l+l- final state

Understand

Results are presented from a search for a narrow, spin-2 resonance decaying into a pair of Z bosons, with one Z-boson decaying into leptons (e+e- or mu+mu-) and the other into jets.

• An example of such a resonance is the Kaluza--Klein graviton, G[KK], predicted in Randall--Sundrum models.
• The analysis is based on a 4.9 inverse femtobarn sample of proton-proton collisions at a center-of-mass energy of 7 TeV, collected with the CMS detector at the LHC.
• Kinematic and topological properties including decay angular distributions are used to discriminate between signal and background.
