论文摘要
我们概述了与爱丽丝探测器的PP和PB-PB碰撞中的JET测量结果。爱丽丝使用抗$ k _ {\ mathrm {t}} $算法在中期重建喷气机,包括来自爱丽丝跟踪探测器的带电粒子喷头,以及来自爱丽丝电气电磁量热量与跟踪系统的爱丽丝电磁量热量的结合。我们专注于包容性和半熟悉的喷气测量以及喷气子结构测量值,包括各种修饰和未修饰的观测值。在PP碰撞中,这些结果在$ p _ {\ mathrm {t,\; jet}}} <140 $ gev $/c $中测试PQCD技术在低堆积环境中,并且可以限制非扰动效果的模型。在PB-PB碰撞中,这些测量测试模型的Quark-Gluon等离子体中的喷射淬火模型,可用于约束高温QCD物质的性质。
We overview recent jet measurements in pp and Pb-Pb collisions with the ALICE detector. ALICE reconstructs jets at midrapidity using the anti-$k_{\mathrm{T}}$ algorithm, including both charged particle jets from the ALICE tracking detectors, and full jets from the combination of the ALICE electromagnetic calorimeter with the tracking system. We focus on inclusive and semi-inclusive jet measurements as well as jet substructure measurements, including a variety of groomed and ungroomed observables. In pp collisions, these results test pQCD techniques at $p_{\mathrm{T,\;jet}}<140$ GeV$/c$ in a low pileup environment, and can constrain models of non-perturbative effects. In Pb-Pb collisions, these measurements test models of jet quenching in the quark-gluon plasma, and can be used to constrain the properties of high temperature QCD matter.
