SU的质量结构（3）重子反十重态和π介子μ子质量差
The mass structure of SU(3) baryon antidecuplet and pion muon mass difference
摘要：
结果表明，SU（3）反十重态中的五夸克重子$Θ^{+}$、$N^{*}(1685)$和$Ξ_{3/2}^{-}$的质量间隔是中性π介子和μ介子质量差的整数倍，即29.318 MeV，这与基本粒子之间质量差接近该质量单位的整数倍/半整数倍的一般趋势相一致.我们的进一步研究表明，SU（3）破缺的强度被理解为给予相同多重态的不同质量的成员，其值离散为中性π介子和μ介子（前两个大质量基本粒子）之间质量差的整数倍。
英文摘要：
We show that the mass intervals among the pentaquark baryons $Θ^{+}$, $N^{*}(1685)$ and $Ξ_{3/2}^{-}$ proposed to be the members of the SU(3) antidecuplet are exact integral multiples of the mass difference between a neutral pion and a muon i.e. 29.318 MeV, in agreement with the general tendency of the mass differences among elementary particles to be close integral/half integral multiple of this mass unit. Further our study reveals that the strength of the SU(3) breaking understood to give members of the same multiplet different masses takes values, discrete as integral multiple of the mass difference between a neutral pion and a muon, the first two massive elementary particles.
