相对论夸克模型中轻介子的质量谱和Regge轨线

Mass spectra and Regge trajectories of light mesons in the relativistic quark model

D. Ebert, R. N. Faustov, V. O. Galkin

摘要:

在基于准势方法的相对论夸克模型框架下,计算了由轻(u,d,s)夸克组成的夸克-反夸克介子的基态、轨道和径向激发态的质量.轻夸克动力学的相对论处理结果在质量谱同意与现有的实验数据的质量最完善的国家。构造了角激励和径向激励下的Regge轨迹,并验证了它们的线性、平行性和等距性。实验观察到的轻介子分配到特定的Regge轨迹是基于它们的质量和量子数。

英文摘要:

Masses of the ground, orbitally and radially excited states of quark-antiquark mesons composed from the light (u,d,s) quarks are calculated within the framework of the relativistic quark model based on the quasipotential approach. The relativistic treatment of the light quark dynamics results in mass spectra which agree well with available experimental data for the masses of the most well-established states. The Regge trajectories for angular and radial excitations are constructed, and their linearity, parallelism and equidistance are verified. The assignment of experimentally observed light mesons to particular Regge trajectories is based on their masses and quantum numbers.
