3rd workshop on the XYZ particles

1 Apr 2015, 08:00 → 3 Apr 2015, 18:00 Asia/Shanghai

主楼C305 (中科院高能所)

Changzheng Yuan (IHEP, Beijing) , Xiaoyan Shen (IHEP)

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5/fb数据，无疑将为XYZ粒子的研究提供重要实验信息。 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和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都非常成功。在征求了部分专家意见后，我们定于2015年4月1-3日在高能所举办第三届研讨会，特邀请您参会，并欢迎提交相关报告。 研讨会将特别关注BESIII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。
