Ω介子产生的动力学耦合道方法

Dynamical coupled channel approach to omega meson production

Mark W. Paris

摘要:

采用动力学耦合道方法研究了质子与π介子和光子散射诱导的$ω$ -介子产生。通过拟合可用的非极化微分截面数据,在双通道(\on,\pn)计算中固定模型参数,用于非共振和共振对$T$矩阵的贡献。偏振光子束的不对称性的预测和现有的数据进行比较。

英文摘要:

The dynamical coupled channel approach is applied to study the $ω$--meson production induced by pions and photons scattering from the proton. The parameters of the model are fixed in a two-channel (\on,\pn) calculation for the non-resonant and resonant contributions to the $T$ matrix by fitting the available unpolarized differential cross section data. The polarized photon beam asymmetry is predicted and compared to existing data.
