A modular perspective to the jet suppression from a small to large radius in very high transverse momentum jets

Abstract

In this work, we expand the scope of the JETSCAPE framework to investigate the dependence of the jet nuclear modification factor, $R_{AA}$, on the jet radius parameter ($R$) for broader area jet cones, going all the way up to $R$ = 1.0. This study presents a comprehensive analysis of high-$p_T$ inclusive jets extending up to 1 TeV to probe the quark-gluon plasma medium at much shorter distance scales. It focuses on quenching effects observed in the quark-gluon plasma formed during Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV, particularly for the most-central (0-10\%) collisions. Jet-medium interactions represent a pivotal domain of both theoretical and experimental QGP studies, with various models offering different assumptions to describe these phenomena. To illustrate this modular approach, this work computes the nuclear modification factor for inclusive jets via coupling of the MATTER model (which simulates the high virtuality phase of the parton evolution) with the LBT model (which simulates the low virtuality phase of the parton evolution). Additionally, the two successful energy loss models: MARTINI and AdS/CFT are employed to characterize the jet-suppression effectively within the JETSCAPE framework. The results are compared with the experimental data from the ATLAS and CMS detectors, covering jet transverse momentum ($p_T$) ranging from 100 GeV to 1 TeV for ATLAS and 300 GeV to 1 TeV for CMS. The predictions made by the JETSCAPE are consistent in the high $p_T$ range as well as for extreme jet cone sizes, showing deviation within 10-25\%. Our major focus is on calculating the double ratio ($R_{\mathrm{AA}}^{\mathrm{R}}/R_{\mathrm{AA}}^{\mathrm{R}=\mathrm{small}}$) as a function of jet-R and jet-$p_T$, where the experimental results align well with predictions from the JETSCAPE framework.
