Inclusive production cross sections of the possible exotic state X(3872) in proton–proton, pion-proton and proton–antiproton collisions are calculated using a statistical based model, which is previously used to describe inclusive charmed and bottomed hadron production cross sections in the low energy region. With the extensions made here the model is capable to include tetraquarks as well, using the diquark picture of tetraquarks. The evaluated cross section ratio of \(\varPsi (2S)\) and X(3872) at \(\sqrt{s}=7\) TeV agrees well with the measured value.

基本强子碰撞中四夸克态的产生截面

质子-质子、pion-质子和质子-反质子碰撞中可能的奇异状态X (3872) 的包含产生横截面是使用基于统计的模型计算的，该模型以前用于描述包含迷人和底部的强子产生横截面低能区。通过在此处进行的扩展，模型也能够使用四夸克的 diquark 图片来包括四夸克。在\(\sqrt{s}=7\) TeV处评估的\(\varPsi (2S)\)和X (3872) 的横截面比与测量值非常吻合。
