个人简介
代建平,男,博士,副教授,博士生导师。长期从事北京谱仪(BESIII)实验物理数据分析和强子谱唯象理论的研究工作,已在Nat. Commun.,、PRL、JHEP、PRD(Letter)、PRC(Letter)、EPJC、PLB、CPC等期刊上发表学术论文20多篇,主持国家级项目2项、主持省部级项目2项。
研究方向:1.加速器物理实验,本人代表星空在线手机版(大中国区)参与国家大科学装置北京谱仪(BESIII)实验,主要研究物质的基本结构及其之间的相互作用,及可能导致的宇宙中正反物质不对称的CP破缺问题,并寻找可能的超出标准模型的新物理等;2.唯象理论研究,结合国内外的高能粒子物理实验,如BESIII、LHCb、Belle/BelleII实验等,基于有效场论方法开展一些强子谱方面,尤其是奇特强子态产生机制、内部结构、衰变性质等的唯象理论研究。
