论文摘要
最近提议的$ n^*（890）$ 1/2^ - $ $ baryon以风味$ su（3）$ schented进行了研究，该方案与$ k $矩阵单位化，通过适合低能横截面和相移数据。发现$ n^*（890）$在其他渠道中与较低的杆子共存，尽管文献中已经广泛讨论了它们，尽管它们属于不同的八位位，但在$ su（3）$限制中。因此，进一步验证了$ n^*（890）$的存在。
The recently proposed $N^*(890)$ $1/2^-$ baryon is studied in a flavor $SU(3)$ scheme with $K$ matrix unitarization, by fitting to low energy cross section and phase shift data. It is found that $N^*(890)$ co-exists with low lying poles in other channels, which have been extensively discussed in the literature, though they belong to different octets, in the $SU(3)$ limit. Hence the existence of $N^*(890)$ is further verified.
