英文摘要 | The excess events reported by the ATLAS collaboration in the WZ-final state, and by the CMS collaboration in the e(+)e(-) jj, Wh and jj-final states, may be induced by the decays of a heavy boson W' in the 1.8-2 TeV mass range, here modeled via the larger local group SU(2)(L) x SU(2)(R) x U(1)(B-L) in a nonlinear dynamical Higgs scenario. The W'-production cross-section at the 13 TeV LHC is around 700-1200 fb. This framework also predicts a heavy Z' boson with a mass of 2.5-4 TeV, and some decay channels testable in the LHC Run II. We determine the cross-section times branching fractions for the dijet, dilepton and top-pair Z'-decay channels at the 13 TeV LHC around 2.3, 7.1, 70.2 fb, respectively, for M-z' = 2.5 TeV, while one/two orders of magnitude smaller for the dijet/dilepton and top-pair modes at M-z' = 4 TeV. Nonzero contributions from the effective operators, and the underlying Higgs sector of the model, will induce sizeable enhancement in the W+W- and Zh-final states that could be probed in the future LHC Run II. |
