TL;DR
This paper investigates hadron correlations in Pb-Pb collisions at 2.76 TeV using ALICE, revealing bulk structures, long-range correlations, and jet modifications through detailed correlation function analysis.
Contribution
It introduces a comprehensive analysis of di-hadron correlations, including Fourier decomposition and jet-yield modification measurements, advancing understanding of quark-gluon plasma properties.
Findings
Identification of bulk correlation structures in Pb-Pb collisions
Observation of long-range correlations dependent on trigger and pT
Measurement of jet-yield modification factor I_AA
Abstract
Untriggered di-hadron correlations studies are shown which provide a map of the bulk correlation structures in Pb-Pb collisions. Long-range correlations are further studied by triggered correlations which address the dependence on trigger and associated pT. Measured correlation functions are decomposed with a multi-parameter fit and into Fourier coefficients. The jet-yield modification factor I_AA is presented.
