1st workshop on the XYZ particles

9 May 2013, 08:00 → 11 May 2013, 18:00 Asia/Shanghai

北京四季御园国际大酒店

随着Zc(3900)的发现，BESIII正式进入XYZ粒子实验研究的前列。目前BESIII已在Y(4260)和Y(4360)共振峰附近积累了世界上最大的样本，到今年夏天，将拥有约2.5/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，在3月份刘克非教授访问期间，我们探讨了举办一个小型的研讨会专题讨论相关问题的可能。在征求了部分专家意见后，我们定于2013年5月10-11日在北京四季御园国际大酒店举办这个研讨会，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。
