在$\sqrt{s}=1.96$ TeV上寻找$p\bar{p}$碰撞中强相互作用粒子衰变成喷注对的成对产生

Search for pair-production of strongly-interacting particles decaying to pairs of jets in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV

CDF Collaboration

摘要:

我们提出了一个非标准模型的强相互作用粒子,衰变到一对夸克或胶子,导致最终状态与四个强子喷流的配对生产的搜索。我们既考虑了通过中间胶子的非共振产生,也考虑了通过不同的非标准模型中间强相互作用粒子的共振产生。我们使用的数据收集的CDF实验中的质子-反质子碰撞在$\sqrt{s}=1.96$ TeV对应的积分亮度为6.6 fb $^{-1}$。我们发现这些数据与标准模型的预测是一致的。我们报告的限制$σ(p\bar{p}\rightarrow$ { \it jjj} $)$作为假设的中间粒子的质量的函数。在几个共振和非共振过程中的非标准模型粒子的生产截面的上限也来自。

英文摘要:

We present a search for the pair-production of a non-standard-model strongly-interacting particle that decays to a pair of quarks or gluons, leading to a final state with four hadronic jets. We consider both non-resonant production via an intermediate gluon as well as resonant production via a distinct non-standard-model intermediate strongly-interacting particle. We use data collected by the CDF experiment in proton-antiproton collisions at $\sqrt{s}=1.96$ TeV corresponding to an integrated luminosity of 6.6 fb$^{-1}$. We find the data to be consistent with standard model predictions. We report limits on $σ(p\bar{p}\rightarrow$ {\it jjjj}$)$ as a function of the masses of the hypothetical intermediate particles. Upper limits on the production cross sections for non-standard-model particles in several resonant and non-resonant processes are also derived.
