Zhibo Liu, Akira Watanabe

AI总结:

在 holographic QCD 模型中,通过 Pomeron 和 Reggeon 交换计算了弹性 π介子-质子和 π介子-π介子散射的总截面与微分截面,预测结果与实验数据一致。

摘要:

在 holographic QCD 模型中研究了弹性 π介子-质子和 π介子-π介子散射,重点关注 Regge 极限。考虑了分别由 Reggeized $2^{++}$ glueball 和矢量 meson 传播子描述的 Pomeron 和 Reggeon 交换,计算了总截面和微分截面。模型中涉及的可调参数由 π介子-质子总截面的实验数据确定。微分截面无需任何额外参数即可预测,且结果表明我们的预测与数据一致。此外还讨论了 Pomeron 和 Reggeon 贡献的能量依赖性。

英文摘要:

The elastic pion-proton and pion-pion scattering are studied in a holographic QCD model, focusing on the Regge regime. Taking into account the Pomeron and Reggeon exchange, which are described by the Reggeized $2^{++}$ glueball and vector meson propagator respectively, the total and differential cross sections are calculated. The adjustable parameters involved in the model are determined with the experimental data of the pion-proton total cross sections. The differential cross sections can be predicted without any additional parameters, and it is shown that our predictions are consistent with the data. The energy dependence of the Pomeron and Reggeon contribution is also discussed.
