带极差修正的弱束缚关系的应用

Application of the weak-binding relation with range correction

Tomona Kinugawa, Tetsuo Hyodo

摘要:

弱束缚关系是从可观测量研究强子内部结构的一个有用工具。我们在弱束缚关系式中引入了有效射程相当大的射程修正,并证明了射程修正可以扩大弱束缚关系式的适用范围。由于弱束缚关系的低能普适性,它可以用来研究任何不同长度尺度系统的浅束缚态结构。我们将弱束缚关系应用于实际系统,包括强子,超核和原子,并显示范围校正的重要性。

英文摘要:

The weak-binding relation is a useful tool to study the internal structure of hadrons from the observable quantities. We introduce the range correction in the weak-binding relation for the system having a sizable magnitude of the effective range, and show that the applicability of the weak-binding relation can be enlarged by the range correction. Thanks to the low-energy universality, the weak-binding relation can be used to study the structure of shallow bound states in any systems with different length scales. We apply the weak-binding relation to actual systems, including hadrons, hypernuclei, and atoms and show the importance of the range correction.
