The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high p_{T}) hadron trigger in proton-proton and central Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb-Pb collisions. Recoil jet distributions are reported for jet resolution parameter R=0.2, 0.4, and 0.5 in the range 7<p_{T,jet}<140 GeV/c and trigger-recoil jet azimuthal separation π/2<Δφ<π. The measurements exhibit a marked medium-induced jet yield enhancement at low p_{T} and at large azimuthal deviation from Δφ∼π. The enhancement is characterized by its dependence on Δφ, which has a slope that differs from zero by 4.7σ. Comparisons to model calculations incorporating different formulations of jet quenching are reported. These comparisons indicate that the observed yield enhancement arises from the response of the QGP medium to jet propagation.
ALICE合作组报告了在质心能量(\sqrt{s_{NN}} = 5.02) TeV的质子-质子对撞以及中心铅-铅对撞中，对来自高横向动量（高(p_T)）强子触发的带电粒子喷注的半包容分布的测量。采用了一种数据驱动的统计方法来减轻中心铅-铅对撞中大量不相关的背景。报告了在(7 < p_{T,jet} < 140) GeV/c范围内，喷注分辨率参数(R = 0.2)、(0.4)和(0.5)，以及触发-反冲喷注方位角间隔(\frac{\pi}{2} < \Delta\varphi < \pi)时的反冲喷注分布。测量结果显示，在低(p_T)以及与(\Delta\varphi \sim \pi)有大方位角偏差时，有明显的介质诱导喷注产额增强。这种增强的特征在于其对(\Delta\varphi)的依赖，其斜率与零的差异为(4.7\sigma)。报告了与纳入不同喷注淬火公式的模型计算的比较。这些比较表明，观察到的产额增强源于夸克胶子等离子体介质对喷注传播的响应。
