报告题目:Charm hadrons decays at BESIII

报 告 人:李蕾 博士

报告摘要By analysing the e+e- annihilation data collected at the centre-of-mass energies of 4.6 GeV, 4.18 GeV and 3.773 GeV, BESIII had published lots of precise and unique measurements on charm hadron decays. These measurements play important and crucial role in calibrating the Lattice QCD calculation, testing the theoretical calculations and understanding the strong and weak interactions involved in charm hadrons. In this talk, some of my studies on charm hadrons, including Lambda_c^+/Ds+/D0, will be introduced. The talk will mainly focus on the studies of Lambda_c^+/Ds+/D0 semi-leptonic decays, the observation of Lambda_c^+ decays to the final states involving neutron and the most precise measurement of charm strong-phase (c_i and s_i) between D0 and D0-bar ->Ks/L pi+pi-.  In addition, some topics about the future plans and prospects on charm hadron decays at BESIII experiment will also be introduced.

报告人简介李蕾,北京石油化工学院数理系副教授。2011年在高能物理研究所获博士学位。2011年-2013年在高能所从事博士后研究工作。2014年入职北京石油化工学院,2016年晋升副教授。2018年获得英国皇家学会牛顿学者研究基金资助(2年),赴牛津大学进行D0与D0-bar强相差测量方面的研究工作。李蕾的研究方向包含粲强子D0/Ds+/Lambda^+_c的半轻子和强子衰变,粲介子D0与D0-bar强相位的测量等。以第一作者和通讯作者在PRL(2篇)、PRD和PLB上累计发表物理文章8篇,作为主要完成人合作发表物理文章4篇。
