dc.description.abstractThe path-length dependent parton energy loss within the dense partonic medium created in lead-lead collisions at a nucleon-nucleon center-of-mass energy of √sNN = 5.02TeV is studied by determining the azimuthal anisotropies for dijets with high transverse momentum. The data were collected by the CMS experiment in 2018 and correspond to an integrated luminosity of 1.69 nb−¹. For events containing back-toback jets, correlations in relative azimuthal angle and pseudorapidity (η) between jets and hadrons, and between two hadrons, are constructed. The anisotropies are expressed as the Fourier expansion coefficients vn, n = 2–4 of these azimuthal distributions. The dijet vn values are extracted from long-range (1.5 < |Δη| < 2.5) components of these correlations, which suppresses the background contributions from jet fragmentation processes. Positive dijet v₂ values are observed which increase from central to more peripheral events, while the v₃ and v₄ values are consistent with zero within experimental uncertainties.es_ES
