论文摘要
在$ \ sqrt {s _ {\ mathrm {nn}}} $ = 5.02 tev中，从pp和pb-pb碰撞中从触发强体和pb-pb碰撞中后退的半分布分布的测量值。该技术提供了喷气测量中大型不相关背景的精确，数据驱动的减法。它可以独特地探索宽相位空间中中型诱导的喷气生产和链球运动的修改，包括低横向动量（$ p_ \ mathrm {t} $）和大分辨率参数（$ r $）喷气机。该程序报告了通过比较PP和PB-PB碰撞中的触发差异后坐力射击产量以及不同$ r $的喷气机，报告了中等诱导的喷射能重新分布。
Measurements of the semi-inclusive distribution of charged jets recoiling from a trigger hadron in pp and Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV are presented. This technique provides precise, data-driven subtraction of the large uncorrelated background in jet measurements. It uniquely enables the exploration of medium-induced modification of jet production and acoplanarity over wide phase space, including low transverse momentum ($p_\mathrm{T}$) and large resolution parameter ($R$) jets. This proceeding reports the measurements of medium-induced jet energy redistribution through the comparison of trigger-normalized recoil jet yields in pp and Pb--Pb collisions, and for jets with different $R$.
