4th workshop on the XYZ particles

22 Nov 2016, 10:00 → 25 Nov 2016, 18:00 Asia/Shanghai

主楼513 （老主楼） (北京航空航天大学)

Changzheng YUAN (IHEP, Beijing) , Chengping SHEN (北航) , Shi-Lin ZHU (Peking University)

随着Zc(3900)的发现，BESIII正式进入XYZ粒子实验研究的前列；随后BESIII又报道了Zc(4020)、Zc(4025)、X(3872)和X(3823)等结果。目前BESIII已在4.0-4.6GeV积累了世界上最大的样本，约9/fb数据，并将于2016-17年度采集更多数据，这些无疑将为XYZ粒子的研究提供重要实验信息。 日本KEK的SuperKEKB加速器2016年第一轮调束已结束，2017年Belle II将开始采集数据，将为XYZ的研究提供更多的机遇。 进一步深入认识XYZ粒子的性质需要理论和实验的密切结合，2013年5月在北京四季御园的第一次研讨会( http://indico.ihep.ac.cn/event/3091/ )，2013年11月20-22日在安徽黄山香茗酒店举办的第二届研讨会( http://indico.ihep.ac.cn/event/3190/ )，和2015年4月1-3日在高能所举办第三届研讨会( http://indico.ihep.ac.cn/event/4780/ )都非常成功。在征求了部分专家意见后，我们定于2016年11月23-25日在北京航空航天大学举办第四届研讨会（22日报到及自由讨论），特邀请您参会，并欢迎提交相关报告。 研讨会将特别关注BESIII和Belle II能提供的哪些测量将对理解XYZ性质有重要意义，实验上需要哪些理论的输入以便对数据有更好的理解，哪些特征量可以有效区分粲偶素与奇特态介子等。 会议不收注册费。
