2nd workshop on the XYZ particles

19 Nov 2013, 14:00 → 22 Nov 2013, 18:00 Asia/Shanghai

随着Zc(3900)的发现，BESIII正式进入XYZ粒子实验研究的前列；2013年的国际轻子光子大会上BESIII又报道了Zc(4020)、Zc(4025)和X(3872)的相关结果。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，约3.3/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非常成功。在征求了部分专家意见后，我们定于2013年11月20-22日在安徽黄山香茗酒店举办第二届研讨会，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。
