论文摘要
这项研究表明了群众的估计值以及对pion nucleon的局部衰减宽度的最终状态（四星级）$ s $和$ p $ baryon的共振，低于$ 2 $ gev。这些估计是从粒子数据组最近汇编中包含的数据中获得的。仅考虑$ n $（$ s = 0，i = 1/2 $）和$δ$（$ s = 0，i = 3/2 $）的状态，其中$ s $和$ i $ $表示陌生和issospin。
This study appertains to the extraction of estimates for the masses and for the partial decay widths to pion-nucleon final states of the well-established (four-star) $s$ and $p$ baryon resonances below $2$ GeV. These estimates are exclusively obtained from the data contained in the recent compilation by the Particle Data Group. Only the $N$ ($S=0,I=1/2$) and the $Δ$ ($S=0,I=3/2$) states are considered, where $S$ and $I$ denote strangeness and total isospin, respectively.
