Measuring jet energy loss fluctuations in the quark-gluon plasma via multiparticle correlations

Published 5 Feb 2024 in hep-ph, nucl-ex, and nucl-th | (2402.03512v1)

Abstract: The quark-gluon plasma (QGP) is a high temperature state of matter produced in the collisions of two nuclei at relativistic energies. The properties of this matter at short distance scales are probed using jets with high transverse momentum (pTp_T) resulting from quarks and gluons scattered with large momentum transfer in the earliest stages of the collisions. The Fourier harmonics for anisotropies in the high transverse momentum particle yield, vn(pT)v_n(p_T), indicate the path length dependence of jet energy loss within the QGP. We present a framework to build off of measurements of jet energy loss using vn(pT)v_n(p_T) by characterizing fluctuations in jet energy loss that are currently not constrained experimentally. In this paper, we utilize a set of multivariate moments and cumulants as new experimental observables to measure event-by-event fluctuations in the azimuthal anisotropies of rare probes, and compare them to the azimuthal anisotropies of soft particles. Ultimately, these fluctuations can be used to quantify the magnitude and fluctuations of event-by-event jet energy loss. We relate these quantities to existing multivariate cumulant observables, highlight their unique properties, and validate their sensitivities with a Monte Carlo simulation.
