手征夸克模型下低激发态$J^P=\,1/2^-$,$3/2^-$ $Λ$的磁矩

摘要:

低位自旋宇称$J^P=$ $1/2^-$、$3/2^-$ $Λ$共振(例如$Λ(1405)$ $1/2^-$、$Λ(1520)$ $3/2^-$)的磁矩以及它们的跃迁磁矩使用手征夸克模型来计算。所得结果与非相对论性夸克模型和幺正手征理论的结果进行了比较,其中一些态是通过两个强子耦合通道的动力学及其幺正化产生的.

英文摘要:

The magnetic moments of the low-lying spin-parity $J^P=$ $1/2^-$, $3/2^-$ $Λ$ resonances, like, for example, $Λ(1405)$ $1/2^-$, $Λ(1520)$ $3/2^-$, as well as their transition magnetic moments, are calculated using the chiral quark model. The results found are compared with those obtained from the nonrelativistic quark model and those of unitary chiral theories, where some of these states are generated through the dynamics of two hadron coupled channels and their unitarization.
