【 摘 要 】

We report the measurement of semi-inclusive pTspectra of charged particle jets that recoil from a high-pThadron trigger in Pb-Pb and pp collisions at and , respectively. In this analysis, the copious yield of uncorrelated trigger hadron-jet matchings in central Pb-Pb collisions is removed by calculating the difference between two spectra corresponding to exclusive trigger hadron pTranges. This procedure does not impose any fragmentation bias on the recoil jet population, which is therefore collinear and infrared safe. The resulting distributions obtained for different values of jet resolution parameter are used to study the modification of jet structure in the medium.
