Cover Story(Issue 9,2025):Precise measurement of the χ_(c 0) resonance parameters and branching fractions o fχ_(c 0,c 2)→π^(+)π^(−)/K^(+)K^(−)
摘要
Charmonia are bound states of charm quark and anti-quark.High precision measurements of their properties provide crucial information for us to understand their internal structures and the underlying dynamics of the hadron formation.For low-lying charmonia with masses below the DD threshold,their decay to light hadrons proceeds predominantly through the annihilation of the charm quark and antiquark into gluons.Since gluons are flavor neutral,the decay pattern of charmonia to light hadrons can be used to test the flavor SU(3)symmetry and its possible breaking owing to the quark mass difference.
