双部分子散射的强子结构

Hadronic structure from double parton scattering

Matteo Rinaldi, Federico Alberto Ceccopieri

摘要:

在本文中,我们考虑了所谓的有效截面,一个量,编码的实验知识的双部分子散射的强子碰撞,已容纳至今。我们表明,有效的截面,在某些假设下,通过在其实验提取接近,可以用来获得一个范围内的平均横向距离的相互作用的部分子对的双重部分子散射。因此,我们证明了有效截面提供了一种获取强子结构信息的途径。

英文摘要:

In the present paper we consider the so-called effective cross section, a quantity which encodes the experimental knowledge on double parton scattering in hadronic collisions that has been accomulated so far. We show that the effective cross section, under some assumptions close to those adopted in its experimental extractions, can be used to obtain a range of mean transverse distance between an interacting parton pair in double parton scattering. Therefore we have proved that the effective cross section offers a way to access information on the hadronic structure.
