论文摘要
在这一贡献中,我们将简要概述横向动量依赖性方法(TMD)方法,作为研究高能(UN)极化强开始碰撞中Hadroon的3维结构的工具。然后,我们将通过研究Quarkonium(主要是$ j/ψ$),Pion和$ d $ -Meson生产的Proton Proton-Proton Collisions的Quarkonium(主要是$ j/ψ$),旨在通过研究Quarkonium(主要是$ j/ψ$)的单个旋转不对称性来限制较差的横向动量依赖的Gluon Sivers功能的目前状态,该研究计划的当前状态。最后,我们将很快讨论有关这一研究领域的观点,特别强调了其在LHC物理计划中的作用,在固定目标设置和NICA中。
In this contribution, we will present a short overview of the transverse momentum dependent (TMD) approach as a tool for studying the 3-dimensional structure of hadrons in high-energy (un)polarized hadron collisions. We will then summarize the present status of a running research programme that aims at constraining the poorly known transverse momentum dependent gluon Sivers function, through the study of single spin asymmetries in quarkonium (mainly $J/ψ$), pion, and $D$-meson production in polarized proton-proton collisions at RHIC. Finally, we will shortly discuss perspectives for this field of research, emphasizing in particular its role in the physics programme of LHC in the fixed-target setup and NICA.
