Abstract:
The ALICE Collaboration reports measurements of the large relative transverse momentum (k_{T}) component of jet substructure in pp and Pb-Pb collisions at center-of-mass energy per nucleon pair sqrt[s_{NN}]=5.02 TeV. Enhancement in the yield of such large-k_{T} emissions in head-on Pb-Pb collisions is predicted to arise from partonic scattering with quasiparticles of the quark-gluon plasma. The analysis utilizes charged-particle jets reconstructed by the anti-k_{T} algorithm with resolution parameter R=0.2 in the transverse-momentum interval 60
