Аннотация:A new method is proposed for determining the coefficient of elliptic anisotropy of jets in ultrarelativistic heavy-ion collisions. This method, which does not involve directly reconstructing the reaction plane, is a generalization of the method used in current experiments to measure the coefficient of elliptic anisotropy of particle fluxes. It is shown that, for the spectrum of hadronic jets, the method makes it possible to explore the azimuthal asymmetry caused by the rescattering of hard partons and by their energy losses in dense quark-gluon matter formed in the region of the initial overlap of nuclei in collisions at a nonzero value of the impact parameter—in particular, under the conditions of the CMS experiment at LHC.
