矩分析方法和五夸克态(英文)

Moment Analysis and Pentaquark State

按照推广的矩分析方法 ,考虑了过程 e+ e- → ψ(2 S)→ ΘΘ,Θ→ K0 p,Θ→ K0 p,给出了 JΘ=1/ 2和 JΘ=3/ 2的不为零的矩表达式 ,这些矩有助于将来在升级的北京正负电子对撞机 /北京谱仪上寻找五夸克态 .

In terms of the generalized moment analysis method, the process e +e -→ψ(2S)→Θ,Θ→K 0p,→K 0 is considered and the expressions of the non-zero moment for J Θ=1/2 and J Θ=3/2 are presented. These non-zero moments would be useful to experimental search for the pentaquark state at upgraded BEPC/BES in the near future.
