一些双部分子散射过程的简要评述

A short review of some double-parton scattering processes

Antoni Szczurek

摘要:

本文还讨论了几个迅速发展的部分子散射场的例子。我们认为两对粲夸克-反夸克的产生是研究双部分子散射效应的黄金反应。我们还简要地讨论了单部分子散射的机制,并指出它对$c \bar c c \bar c$末态的贡献要小得多。在这方面,我们还讨论了微扰部分子分裂机制的贡献,也应该加入到传统的DPS机制。字母的存在导致所谓的$σ_{eff}$的碰撞能量和其他运动学变量依赖性。我们简要地讨论了四个喷气机的生产。我们集中估计DPS的贡献的射流广泛分离的速度。最后简要介绍了DPS在$W^+ W^-$生产中的作用。

英文摘要:

A few examples of quickly developing field of double parton scattering are discussed. We present arguments that the production of two pairs of charm quark-antiquark is the golden reaction to study the double parton scattering effects. We discuss briefly also mechanism of single parton scattering and show that it gives much smaller contribution to the $c \bar c c \bar c$ final state. In this context we discuss also the contribution of perturbative parton-splitting mechanism which should also be added to the conventional DPS mechanism. The presence of the letter leads to collision energy and other kinematical variables dependence of so-called $σ_{eff}$. We briefly discuss production of four jets. We concentrate on estimation of the contribution of DPS for jets widely separated in rapidity. Finally we briefly mention about DPS effects in production of $W^+ W^-$.
