窄的无味介子是新物理学的标志吗?

Are narrow unflavoured mesons a signature of new physics?

Boris Tatischeff, Egle Tomasi-Gustafsson

摘要:

给出了窄低质量无味介子结构的新数据。一个表,这些外来群众获得增加以前公布的数据。质量序列显示了这些团簇中的一些与稳定强子(π介子、核子和氘核)的显着耦合。事实上,这种耦合可以相当好地再现奇异的窄重子和双重子的质量。讨论提出了一种可能的解释,这些异国情调的强子结构。

英文摘要:

New data of narrow low mass unflavoured mesonic structures are presented. A table of these exotic masses is obtained adding previously published data. The mass sequence shows a significant coupling of some of these clusters with stable hadrons: pion, nucleon, and deuteron. Indeed this coupling allows to reproduce rather well the masses of exotic narrow baryons and dibaryons. A discussion is presented to suggest a possible interpretation of these exotic hadronic structures.
