Abstract:	摘要： (ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) Abstract A search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos. The analysis uses a data sample of pp collisions corresponding to an integrated luminosity of 5 fb^sup -1^ collected by the CMS experiment at the LHC at ... TeV in 2011. No significant excess is observed in the mass distribution of the VZ candidates compared with the background expectation from standard model processes. Model-dependent upper limits at the 95% confidence level are set on the product of the cross section times the branching fraction of hypothetical particles decaying to the VZ final state as a function of mass. Sequential standard model W^sup '^ bosons with masses between 700 and 940 GeV are excluded. In the Randall-Sundrum model for graviton resonances with a coupling parameter of 0.05, masses between 750 and 880 GeV are also excluded.[Figure not available: see fulltext.] 出版者： Heidelberg: Springer Nature B.V 出版日期： 2013-02-01 出處： The journal of high energy physics, 2013-02, Vol.2013 (2), p.1 資源來源： ProQuest Open Access Content Collection 版權： SISSA, Trieste, Italy 2013 識別號： EISSN: 1029-8479 識別號： DOI: 10.1007/JHEP02(2013)036
