AI总结:

本文通过旁观者模型计算自旋依赖TMD胶子密度,引入基于拟合的旁观者质量调制函数,重点研究Boer-Mulders和Sivers函数,以推动质子三维胶子结构重建。

摘要:

我们展示了旨在通过自旋依赖的TMD胶子密度探测质子三维胶子内容的研究,这些密度通过旁观者模型方法计算得到。我们的形式体系引入了一个基于拟合的旁观者质量调制函数,旨在捕捉宽广运动学范围内的纵向动量效应。特别强调了时间反演偶的Boer-Mulders函数和时间反演奇的Sivers函数。准确理解这些函数对于开展核子的精确三维分析至关重要,这凸显了LHC与EIC共同体之间合作努力的重要性。

英文摘要:

We present studies aimed at probing the 3D gluon content of the proton through spin-dependent TMD gluon densities, computed by means of the spectator-model approach. Our formalism incorporates a fit-based modulation function for the spectator mass, designed to capture longitudinal-momentum effects across a broad kinematic range. Special emphasis is placed on the time-reversal even Boer-Mulders and the time-reversal odd Sivers functions. Accurate understanding of these functions is crucial for conducting precise 3D analyses of nucleons, highlighting the importance of collaborative efforts between the LHC and EIC Communities.
