极高能量下的总光生截面

Total photoproduction cross-section at very high energy

R. M. Godbole, A Grau, G. Pancheri, Y. N. Srivastava

摘要:

在本文中,我们应用到光生总截面的模型,我们已经提出了纯强子过程,这是基于QCD微型喷注和软胶子再求和。我们比较了我们的模型的预测与HERA数据以及与其他模型。对于宇宙射线,我们的模型预测在TeV能量下的横截面比基于因式分解的模型高得多,但比基于单独的微型喷流的模型低,没有软胶子。我们讨论了这种差异的起源。

英文摘要:

In this paper we apply to photoproduction total cross-section a model we have proposed for purely hadronic processes and which is based on QCD mini-jets and soft gluon re-summation. We compare the predictions of our model with the HERA data as well as with other models. For cosmic rays, our model predicts substantially higher cross-sections at TeV energies than models based on factorization but lower than models based on mini-jets alone, without soft gluons. We discuss the origin of this difference.
