结合观测到的异常和暗物质，我们研究了大型强子对撞机测试暗物质、类矢量夸克的能力。我们关注一个具有类矢量双重夸克和复杂单重标量的局域模型，其中最轻的成分是暗物质的候选成分。在施加相关约束后，我们发现暗物质的异常和遗迹丰度对gev和gev有利，对2tev和2tev（重伴星）有利。目前在大型强子对撞机上寻找喷流和缺失的横向动量大大减少了类矢量夸克的质量范围，并且需要大于1.7 TeV。最后，我们讨论了在高亮度的大型强子对撞机上通过QCD处理器探测这些新粒子的可能性。以=1.93 TeV、GeV和145 GeV为基准点，进行了详细的蒙特卡罗模拟，发现该基准点可以在14tev LHC上达到，综合光度为3000fb。
Combining theanomaly and dark matter observables, we study the capability of LHC to test dark matter,, and vector-like quark. We focus on a localmodel with a vector-likedoublet quarkand a complex singlet scalar whose lightest componentis a candidate of dark matter. After imposing relevant constraints, we find that theanomaly and the relic abundance of dark matter favorGeV andGeV for2 TeV and2 TeV (the heavy partner of). The current searches for jets and missing transverse momentum at the LHC sizably reduce the mass ranges of the vector-like quark, andis required to be larger than 1.7 TeV. Finally, we discuss the possibility of probing these new particles at the high luminosity LHC via the QCD processorfollowed by the decayorand then. Taking a benchmark point of=1.93 TeV,GeV, and145 GeV, we perform a detailed Monte Carlo simulation, and find that such benchmark point can be accessible at the 14 TeV LHC with an integrated luminosity 3000 fb.
