摘要:

提出了一个基于Regge理论的光生矢量介子模型。我们拟合了SLAC数据,预测了在$E_γ\sim 8.5$ GeV下$ω$、$ρ^0$和$ϕ$介子光生过程中自旋密度矩阵元的能量和动量转移依赖关系,这是Jefferson实验室即将测量的结果.

英文摘要:

We propose a model based on Regge theory to describe photoproduction of light vector mesons. We fit the SLAC data and make predictions for the energy and momentum transfer dependence of the spin-density matrix elements in photoproduction of $ω$, $ρ^0$ and $ϕ$ mesons at $E_γ\sim 8.5$ GeV, which are soon to be measured at Jefferson Lab.
