Abstract:	摘要： Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top quark (the top squark) and the Higgs boson (Higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 fb-1 of proton-proton collision data at s=8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the top squark mass below 360 to 410 GeV, depending on the Higgsino mass. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society (APS) 出版日期： 2014-04-25 出處： Physical Review Letters, 2014-04, Vol.112 (16), p.161802, Article 161802 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： ISSN: 1092-0145 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/physrevlett.112.161802 識別號： PMID: 24815637
