论文摘要

众所周知,盖尔·曼(M. Gell-Mann)于1964年介绍了夸克(Quarks),以描述已知的介子和重子,暗示存在$ qq \ bar q \ bar q $ mesons(tetraquarks)和$ qqqq \ bar q $ q $ baryons(pentaquarks)(pentraquarks)(pentaquarks)。 1977年,R。Jaffe提出了一个最轻的标量介子的模型,作为Diquark-Antidiquark Pairs和A. de Rujula,H。Georgi和S. Glashow创造了术语Hadon Molecules,以描述由熟悉的核力量束缚的Meson-Antimeson对制成的可能的HADRON。两张替代图片已被用来解释Belle在2003年发现的意外的强子,即Babar证实的$ X(3872)$,并在许多其他高能量实验中看到。从那时起,已经发现了大量异国情调的哈子,经典的盖尔·曼(Gell-Mann)无法描述的介子和重子,$ q \ bar q $和$ qQQ $,配置,开放了Hadron Spectroscopery的新章节。

It is well known that M. Gell-Mann, introducing quarks in 1964 to describe the known mesons and baryons, hinted at the existence of further $qq\bar q\bar q$ mesons (tetraquarks) and $qqqq\bar q$ baryons (pentaquarks). In 1977, R. Jaffe proposed a model of the lightest scalar mesons as diquark-antidiquark pairs and A. de Rujula, H. Georgi and S. Glashow coined the term hadron molecules, to describe possible hadrons made by meson-antimeson pairs bound by the familiar nuclear forces, also an overall tetraquark system. The two alternative pictures have been employed to interpret the unexpected hadron discovered by Belle in 2003, the $X(3872)$, confirmed by BaBar and seen in many other High Energy experiments. Since then, a wealth of Exotic Hadrons have been discovered, mesons and baryons that cannot be described by the classical Gell-Mann, $q\bar q$ and $qqq$, configurations, opening a new chapter of Hadron Spectroscopy.
