质子-质子散射中的库仑-核干涉效应:一种简单的新程函方法

Coulomb-nuclear interference effects in proton-proton scattering: A simple new eikonal approach

Loyal Durand, Phuoc Ha

摘要:

本文提出了一种简单的新方法,在散射振幅的程函模型的背景下处理高能质子-质子散射中的库仑核干涉和形状因子效应。我们表明,核和库仑振幅的修正不依赖于灵敏的程函振幅的细节,可以被视为普遍的,并提出参数化的必要的修正。我们还提出了一个简单的核散射振幅模型,用于小动量转移时的数据分析,该模型建立在适当的核相位和振幅实部和虚部的衍射零点中。

英文摘要:

We present a simple new approach to the treatment of Coulomb-nuclear interference and form-factor effects in high-energy proton-proton scattering in the context of eikonal models for the scattering amplitude. We show that the corrections to the nuclear and Coulomb amplitudes do not depend sensitively on the details of the eikonal amplitude and can be taken as universal, and present parametrizations for the necessary corrections. We also present a simple model for the nuclear scattering amplitude useful for data analysis at small momentum transfer which builds in the proper nuclear phase and the diffraction zeros in the real and imaginary parts of the amplitude.
