标题： Jet substructure measurements elucidating partonic evolution in $p$+$p$ collisions at RHIC

摘要： 喷注是多尺度物体，将部分子连接到强子，使得喷注结构测量对于研究QCD中的微扰和非微扰过程至关重要。 在STAR实验中，各种喷注结构可观测量，如SoftDrop去噪分裂和N点能量关联函数（ENC），提供了关于部分子演化和强子化机制的见解。 SoftDrop去噪可观测量和ENC都能将测量与部分子层面的基本QCD联系起来，允许与第一性原理理论计算进行比较。 此外，通过还包括电荷信息，如电荷加权的ENC，可以获得关于强子化机制的细节。 在这些会议论文中，我们展示了在$p$+$p$碰撞中不同喷注动量和半径下SoftDrop可观测量和ENC的初步测量结果，能量约为$\sqrt{s}$~=~200~GeV，使用STAR数据。 显示英文摘要

摘要： Jets are multiscale objects that connect partons to hadrons, making jet substructure measurements crucial for probing both perturbative and non-perturbative processes in QCD. At STAR, a variety of jet substructure observables, such as SoftDrop groomed splittings and N-Point Energy Correlators (ENC), provide insights into parton evolution and hadronization mechanisms. SoftDrop-groomed observables and ENCs both connect measurement to fundamental QCD at the parton level, allowing for comparisons to first-principles theoretical calculations. Additionally, by also including charge information, as in the charge-weighted ENC, details about the hadronization mechanism can be obtained. In these proceedings, we present preliminary results on measurements of SoftDrop observables and ENCs across different jet momenta and radii in $p$+$p$ collisions at $\sqrt{s}$~=~200~GeV using STAR data.
