Four Jets as a Probe of O(100 GeV) Physics beyond Standard Model at Hadron Colliders

الأصل · EN

O(100 GeV) physics beyond the standard model (BSM) could be overlooked provided that it is hidden in the untouched Higgs sector or jets. The top quark forward-backward asymmetry measurements and di-jet bump, which is observed in the associated production with charged lepton plus missing energy (supposed arising from W decay), may indicate the existence of a new color-octet axial-vector ZC with a mass about 145 GeV. Here ZC only decays into two jets. In this paper we investigated the possibility to discover ZC pair via analyzing the four jets as the final states, which are heavily polluted by huge QCD background. Our simulation showed that, however, both Tevatron and LHC have the excellent chance to discover ZC through analyzing the four jets events in the current accumulated data.
