冷核物质中的$Φ$和$J/Ψ$介子

$Φ$ and $J/Ψ$ Mesons in Cold Nuclear Matter

J. J. Cobos-Martínez, K. Tsushima, G. Krein, A. W. Thomas

摘要:

我们提出了$Φ$ -和$J/Ψ$ -核束缚态能量和吸收宽度为一些选定的核,使用潜在的局部密度近似计算从一个有效的拉格朗日方法结合夸克-介子耦合模型。我们的结果表明,这些介子应形成束缚态的所有核考虑,只要这些介子产生在近无反冲运动学。

英文摘要:

We present $Φ$- and $J/Ψ$--nuclear bound state energies and absorption widths for some selected nuclei, using potentials in the local density approximation computed from an effective Lagrangian approach combined with the quark-meson coupling model. Our results suggest that these mesons should form bound states with all the nuclei considered provided that these mesons are produced in nearly recoilless kinematics.
