经过北京正负电子对撞机（BEPCII）和北京谱仪（BESIII）工作人员历时四个月的共同努力，BESIII国际合作组于2015年5月1日圆满完成低能区2-3GeV取数计划。本轮实验的物理目标是R值测量及低能区QCD相关研究，取数能量点从3.08GeV一直延伸到BEPCII的低限2.0GeV，对加速器运行是一个挑战。在加速器与谱仪工作人员的密切合作下，不仅按计划完成了19个能量点的对撞取数及其中两个...

The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
the chiral transition (2+1)-flavor QCD
2011/1/6
We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light quark chemical potential. We show that for small values of the chemical potential the curvature of the p...

Analysis of the $N_f=2+1$ lattice QCD results on the lowest-lying baryon masses using covariant ChPT
the $N_f=2+1$ lattice QCD results lowest-lying baryon masses
