CERN-LHC. Search for a new heavy particle produced in association with a top or antitop quark in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data set used is the full 2011 data set with a total integrated luminosity of 4.7 fb-1. The paper considers two models in which a new heavy particle is a colour singlet (WPRIME model) or a colour triplet (PHI model) decaying respectively into TBAR-Q or T-Q which lead to a resonance within the TTBAR+JETS signature. The tables here give the numerical values of the upper limits of the heavy particle cross sections and couplings for each model.

欧洲核子研究中心大型强子对撞机（CERN-LHC）开展的物理分析：在质心系能量为7 TeV的质子-质子对撞（proton-proton collisions）中，搜寻伴随顶夸克（top quark）或反顶夸克（antitop quark）产生的新型重粒子。本次分析采用2011年全年采集的全部数据集，总积分亮度（integrated luminosity）为4.7 fb⁻¹。本研究考量两类模型：新型重粒子分别为色单态（colour singlet，WPRIME模型）与色三重态（colour triplet，PHI模型），二者分别衰变至反顶夸克-夸克与顶夸克-夸克末态，进而在TTBAR+JETS信号特征中产生共振峰。本文附表给出了两类模型下重粒子产生截面（cross section）与耦合常数（couplings）的上限数值。
