X(3915)和X(4350)强衰变的估算

Estimating strong decays of X(3915) and X(4350)

Zhao Zi-Jia, Pan Dong-Mei

摘要:

本文假设X(3915)和X(4350)为P波粲偶素态,研究了它们的强衰变。我们利用D(*)D(*)开魅中间态估计了Γ(X(3915)\to J/ω)和Γ(X(4350)\to J/ω).我们的计算支持X(4350)归属粲偶素态,而X(3915)归属粲偶素态是不利的。

英文摘要:

Strong decays of X(3915) and X(4350) have been studied by assuming them as P-wave charmonium states. We estimate the Γ(X(3915) \to J/ψω) and Γ(X(4350) \to J/ψϕ) via D(*)D(*)open-charm intermediate states. Our calculation supports that the assignment of X(4350) to the charmonium state while the assignment of X(3915) is disfavored.
