    Azimuthal anisotropy of jet quenching at LHC

    Get PDF
    We analyze the azimuthal anisotropy of jet spectra due to energy loss of hard partons in quark-gluon plasma, created initially in nuclear overlap zone in collisions with non-zero impact parameter. The calculations are performed for semi-central Pb-Pb collisions at LHC energy.Comment: Talk given at Fourth International Conference "Physics and Astrophysics of Quark-Gluon Plasma", November 26-30, 2001; 4 pages including 4 eps-figure

    Jet quenching

    We present a comprehensive review of the physics of hadron and jet production at large transverse momentum in high-energy nucleus-nucleus collisions. Emphasis is put on experimental and theoretical "jet quenching" observables that provide direct information on the (thermo)dynamical properties of hot and dense QCD matter.Comment: Springer Verlag.
