论文摘要
这项研究重新讨论了质量提取估计值的问题,以及对标量 - 等距$ i^g \ to to的部分衰减宽度的问题,(j^{pc})= 0^+\,(0^{++})$和vector-isovector $ i^g \ i^g \,(j^)低于$ 2 $的GEV,来自粒子数据组最近汇编中包含的数据。
This study revisits the issue of the extraction of estimates for the masses and for the partial decay widths to two pions of the scalar-isoscalar $I^G\,(J^{PC}) = 0^+\,(0^{++})$ and vector-isovector $I^G\,(J^{PC}) = 1^+\,(1^{--})$ mesons below $2$ GeV, from the data contained in the recent compilation by the Particle Data Group.
