Summary, in English

The ALICE Collaboration reports measurements of the large relative transverse momentum (kT) component of jet substructure in pp and Pb-Pb collisions at center-of-mass energy per nucleon pair sNN=5.02 TeV. Enhancement in the yield of such large-kT 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-kT algorithm with resolution parameter R=0.2 in the transverse-momentum interval 60
