用共振手征理论模拟标量介子动力学

On modeling the scalar meson dynamics with Resonance Chiral Theory

S. Ivashyn, A. Korchin

摘要:

本文讨论了共振手征理论(RChT)对最轻标量共振σ,f0(980)和a0(980)的描述。本文着重讨论了φ(1020)介子辐射衰变中不变质量分布的拟合。RChT中标量扇区的研究是由理论预测能力在具有其他类型共振的许多过程中的成功所激发的。我们的结论是,RChT是足够灵活的描述这些衰变,但需要进一步的定量改进。概述了技术工作和有关的重要问题。

英文摘要:

The features of the Resonance Chiral Theory (RChT) related to the description of the lightest scalar resonances, sigma, f0(980) and a0(980), are discussed. Major attention is paid to the fits of the invariant mass distributions in the radiative decays of the phi(1020) meson. The study of the scalar sector in RChT is motivated by the success of the theory predictive power in numerous processes with other types of resonances. We conclude that RChT is sufficiently flexible to describe these decays, however the further quantitative improvement is required. The technical work-outs and related important questions are outlined.
