Search for neutral resonances decaying into a Z boson and a pair of b jets or tau leptons

Understand

A search is performed for a new resonance decaying into a lighter resonance and a Z boson.

• Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged tau leptons or a b b-bar pair.
• The Z boson is identified via its decays to electrons or muons.
• The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 inverse femtobarns.
