轻、中标量介子的多道描述

Multichannel Description of Light and Intermediate Scalar Mesons

Susana Coito, George Rupp, Eef van Beveren

摘要:

本文简要回顾了轻标量介子的各种研究方法,以及它们在共振谱展开和相关耦合通道理论中的描述。最近的多通道模型的光标量扩展到更高的能量和额外的衰变通道,允许作出预测的中间标量介子以及。进一步改进的前景进行了讨论。PACS编号:14.40.Cs、14.40.Ev、11.80.Gw、11.55.Ds、13.75.Lb

英文摘要:

The light scalar mesons in a variety of approaches are briefly reviewed, as well as their description in the Resonance-Spectrum Expansion and related coupled-channel formalisms. A recent multichannel modelling of the light scalars is extended to higher energies and with additional decay channels, allowing to make predictions for the intermediate scalar mesons as well. Prospects for further improvements are discussed. PACS numbers: 14.40.Cs, 14.40.Ev, 11.80.Gw, 11.55.Ds, 13.75.Lb
