Description
Abstract: Glueballs, hybrids and multiquark states are hadrons of new forms that are supported by the QCD theory but not yet established in experiment. Search and study of new hadrons therefore play a crucial role in testing and improving understanding of the QCD theory. BESIII has collected the world largest J/psi and psi' data samples.
Their decays provide great opportunities to study light hadron spectroscopy, where ground states of new hadrons are predicted to be accessible. This talk reviews some highlights of BESIII results on search and study new light hadrons, and discusses further studies on this subject.
简介：QCD理论支持强子以胶球、混杂态和多夸克态等形式存在，然而实验上迄今尚未明确证实这点。研究新型强子对检验和增进理解QCD理论至关重要。理论预言新型强子的基态存在于轻强子谱中。BESIII实验采集了世界上最大的J/psi和psi'样本，它们的衰变提供了理想的研究轻强子谱的环境。本报告回顾了BESIII实验上搜寻和研究新型轻强子的部分主要成果，展望了未来BESIII在该领域的发展。
