Search for exotic resonances decaying into WZ/ZZ in pp collisions at sqrt(s) = 7 TeV

Understand

A search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos.

• The analysis uses a data sample of pp collisions corresponding to an integrated luminosity of 5 inverse femtobarns collected by the CMS experiment at the LHC at sqrt(s) = 7 TeV in 2011.
• No significant excess is observed in the mass distribution of the VZ candidates compared with the background expectation from standard model processes.
• Model-dependent upper limits at the 95% confidence level are set on the product of the cross section times the branching fraction of hypothetical particles decaying to the VZ final state as a function of mass.
