工作中的动态疏导:从p+p到Pb+Pb

Dynamical grooming at work: from p+p to Pb+Pb

Alba Soto-Ontoso

摘要:

我们提出了一个定量的比较两种疏导技术:软滴(SD)和动态疏导(DyG),在其相关的观测到的潜在事件,强子化和堆积在$\sqrt s\!=\! 13$ TeV的质子-质子碰撞的弹性。为此,我们研究了QCD喷流中的修饰动量分数$z_g$以及增强的W标记。此外,为了评估重离子碰撞中SD和DyG观测量对夸克-胶子等离子体(QGP)效应的敏感性,我们还在几种喷注淬灭的Monte-Carlo模型中得到了修整动量角$R_g$.

英文摘要:

We present a quantitative comparison between two grooming techniques: SoftDrop (SD) and Dynamical Grooming (DyG), in terms of the resilience of their associated observables to the underlying event, hadronization and pileup in proton-proton collisions at $\sqrt s\!=\! 13$ TeV. For that purpose, we study the groomed momentum fraction, $z_g$, in QCD jets along with boosted W tagging. In addition, we obtain the groomed momentum angle, $R_g$, within several jet quenching Monte-Carlo models in order to asses the sensitivity of SD and DyG observables to quark-gluon plasma (QGP) effects in heavy-ion collisions.
