| 英文摘要 | A search for heavy resonances decaying to a pair of z bosons is performed using data collected with the cms detector at the lhc. events are selected by requiring two oppositely charged leptons (electrons or muons), consistent with the decay of a z boson, and large missing transverse momentum, which is interpreted as arising from the decay of a second z boson to two neutrinos. the analysis uses data from proton-proton collisions at a center-of-mass energy of 13 tev, corresponding to an integrated luminosity of 35.9 fb(-1). the hypothesis of a spin-2 bulk graviton (x) decaying to a pair of z bosons is examined for 600 <= m(x) <= 2500 gev and upper limits at 95% confidence level are set on the product of the production cross section and branching fraction of x -> zz ranging from 100 to 4 fb. for bulk graviton models characterized by a curvature scale parameter (k) over tilde = 0.5 in the extra dimension, the region nix < 800 gev is excluded, providing the most stringent limit reported to date. variations of the model considering the possibility of a wide resonance produced exclusively via gluon-gluon fusion or q<(q)over bar> annihilation are also examined. |
