替代大Nc格式与手征动力学

Alternative Large Nc Schemes and Chiral Dynamics

Francesco Sannino, Joseph Schechter

摘要:

我们比较了单指数夸克场和双指数夸克场的主导π介子散射振幅对颜色数的依赖性。这些被认为是有不同的关系,散射振幅建议手征动力学,可以解释长令人费解的π介子s波散射高达约1 GeV。这可能是有趣的更好地了解大NC的方法,以及应用到最近提出的彩色模型。

英文摘要:

We compare the dependences on the number of colors of the leading pion pion scattering amplitudes using the single index quark field and two index quark fields. These are seen to have different relationships to the scattering amplitudes suggested by chiral dynamics which can explain the long puzzling pion pion s wave scattering up to about 1 GeV. This may be interesting for getting a better understanding of the large Nc approach as well as for application to recently proposed technicolor models.
