论文摘要
事实证明，夸克模型成功地描述了标准模型中强烈相互作用粒子的基本构建块，在标准模型中，耐药状态由夸克和胶子组成。同时，Lattice QCD预测了质量范围\ Mbox {1550---1750} Mev/$ c^2 $的粘合球候选者的可能性，这是从未被观察到的。对没有夸克含量的介子的存在的实验搜索既有趣又具有挑战性，因为粘合球很可能与周围的夸克 - 易药标量梅森状态混合在一起，具有相同的量子数。爱丽丝（Alice）在最高LHC质量中心能量的PP碰撞中收集的大型统计数据样本为测量高质量共振的机会提供了机会，其特征和内部结构仍然未知。在本文中，我们使用K $^{0} _ \ Mathrm {s} \ Mathrm {K}^{0} _ \ Mathrm {s} _ {S} $ {S} $ {s $^$^{+k $ k $ k $ k $^ativies $ \ sqrt {s} $ = 13 TEV使用Alice检测器处于中等范围。
The quark model has proven successful in describing the basic building blocks of strongly interacting particles in the Standard Model, where hadronic states consist of quarks and gluons. At the same time, Lattice QCD predicts the possibility of glueball candidates in the mass range \mbox{1550--1750} MeV/$c^2$, which have never been observed. The experimental search for the existence of mesons with no quark content is both interesting and challenging as the glueball is very likely to mix with surrounding quark-antiquark scalar meson states with the same quantum numbers. The large statistics data sample collected by ALICE in pp collisions at the highest LHC center-of-mass energy provides an opportunity to measure high mass resonances, whose characteristics and internal structure are still unknown. In this article, we report on the measurements of invariant mass distributions of higher mass resonances using the decay channels of K$^{0}_\mathrm{S}\mathrm{K}^{0}_\mathrm{S}$ and K$^{+}$K$^{-}$ pairs in pp collisions at $\sqrt{s}$ = 13 TeV using ALICE detector at midrapidity.
