重子和引力球模型中的有质量闭弦

Closed String with Masses in Models of Baryons and Glueballs

G. S. Sharov

摘要:

带有$n$点状质量的闭弦被认为是重子($n=3$)、胶球($n=2$或3)或另一种奇异强子的模型。对于这个系统的转动状态的获得和分类。它们对应于动力学方程的精确解,描述了带质量点的弦的均匀旋转。这些转动态导致一组具有不同行为的准线性Regge轨迹。用小扰动分析方法解决了所谓中心转动态(转动中心有质量)的稳定性问题。如果中心质量小于某个临界值,这些态就被证明是不稳定的。

英文摘要:

The closed string carrying $n$ point-like masses is considered as the model of a baryon ($n=3$), a glueball ($n=2$ or 3) or another exotic hadron. For this system the rotational states are obtained and classified. They correspond to exact solutions of dynamical equations, describing an uniform rotation of the string with massive points. These rotational states result in a set of quasilinear Regge trajectories with different behavior. The stability problem for the so called central rotational states (with a mass at the rotational center) is solved with using the analysis of small disturbances. These states turned out to be unstable, if the central mass is less than some critical value.
