Search for high-mass Z gamma resonances in proton-proton collisions at sqrt(s) = 8 and 13 TeV using jet substructure techniques

Understand

A search for massive resonances decaying to a Z boson and a photon is performed in events with a hadronically decaying Z boson candidate, separately in light-quark and b quark decay modes, identified using jet substructure and advanced b tagging techniques.

• Results are based on samples of proton-proton collisions collected with the CMS detector at the LHC at center-of-mass energies of 8 and 13 TeV, corresponding to integrated luminosities of 19.7 and 2.7 inverse femtobarns, respectively.
• The results of the search are combined with those of a similar search in the leptonic decay modes of the Z boson, based on the same data sets.
• Spin-0 resonances with various widths and with masses in a range between 0.2 and 3.0 TeV are considered.
