A search is reported for a narrow vector resonance decaying to quark-antiquark pairs in proton-proton collisions at $\sqrt{s}=13\mathrm{TeV}$, collected with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of $2.7{\mathrm{fb}}^{-1}$. The vector resonance is produced at large transverse momenta, with its decay products merged into a single jet. The resulting signature is a peak over background in the distribution of the invariant mass of the jet. The results are interpreted in the framework of a leptophobic vector resonance and no evidence is found for such particles in the mass range of 100–300 GeV. Upper limits at 95% confidence level on the production cross section are presented in a region of mass-coupling phase space previously unexplored at the LHC. The region below 140 GeV has not been explored by any previous experiments.

在质子-质子碰撞ats = 13TeV中搜索减弱到Quark-Antiquark对的低质量矢量共振

据报道，在一个质子-质子碰撞中，一个狭窄的矢量共振衰减到夸克-反夸克对。 $\sqrt{s}=13\mathrm{电视}$，由大型强子对撞机的CMS检测器收集。数据样本对应于$2.7{\mathrm{fb}}^{-\mathrm{1个}}$。矢量共振是在较大的横向动量处产生的，其衰减产物合并为单个射流。产生的特征是在射流不变质量的分布中超过背景的峰值。在疏血矢量共振的框架内解释了结果，并且没有发现质量范围为100–300 GeV的此类粒子的证据。在生产横截面上95％置信水平的上限出现在LHC之前尚未探索的质量耦合相空间区域中。以前的任何实验都未曾探索过低于140 GeV的区域。
