| Özet |
| A search for resonances decaying to top quark-antiquark pairs is performed using a dilepton+ jets data sample recorded by the CMS experiment at the LHC in pp collisions at s√= 7 TeV corresponding to an integrated luminosity of 5.0 fb (− 1). No significant deviations from the standard model background are observed. Upper limits are presented for the production cross section times branching fraction of top quark-antiquark resonances for masses from 750 to 3000 GeV. In particular, the existence of a leptophobic topcolor particle Z′ is excluded at the 95% confidence level for resonance masses M (Z′)< 1.3 TeV for Γ (Z′)= 0.012 M (Z′), and M< 1.9 TeV for Γ (Z′)= 0.10 M (Z′). |
