Regge轨线是拟线性的还是平方根型的?

Is the Regge Trajectory Quasi-linear or Square-root Form?

Zhen Li, Ke-Wei Wei

摘要:

近年来发现了许多轨道激发态介子。在这项工作中,我们试图研究Regge轨迹是否是准线性或平方根形式。在准线性Regge轨线和平方根Regge轨线的框架下,估计了位于已建立的11S0,13S1和13P2轨线上的态的质量.将两种轨道的计算结果与已有的实验数据进行了比较,结果表明它们都能对基态介子进行合理的描述。对于轨道激发态,用准线性轨道描述现有的介子谱更为合理。

英文摘要:

There are many orbital excited mesons discovered in recent years. In this work we attempt to study whether the Regge trajectory is quasi-linear or square-root form. In the framework of the quasi-linear Regge trajectory and square-root Regge trajectory, the masses of the states lying on the well established 11S0, 13S1, and 13P2 trajectories are estimated. Comparison of the results given by the two trajectories with the existing experimental data illustrates that both of them can give a reasonable description for the ground mesons. For the orbital excited states, the quasi-linear trajectory describes the existing meson spectrum to be more reasonable.
