碩士 === 國立中央大學 === 物理學系 === 105 === A search for heavy resonances decaying to a Higgs boson and a Z boson is presented. The analysis is based on the data collected in 2015 with the CMS detector at a center-of-mass energy √s = 13 TeV, corresponding to an integrated luminosity of 2.51 fb-1. The Higgs bosons are reconstructed from high momentum bb quark pairs that are detected as a single massive jet, while the Z bosons are reconstructed from electron pairs and muon pairs. The analysis is separated in electron and muon channels, with single and double b-tag categories. A 95% upper limit on the production cross section of σX × B(X → ZH) is derived from the combination of four categories with a limit of 0.063 pb to 0.265 pb for mX from 800 to 4000 GeV.
