We report the measurement of semi-inclusive p(T) spectra of charged particle jets that recoil from a high-p(T) hadron trigger in Pb Pb and pp collisions at root s(NN) = 2.76 TeV and root s = 7 TeV, respectively. In this analysis, the copious yield of uncorrelated trigger hadronjet matchings in central Pb Pb collisions is removed by calculating the difference between two spectra corresponding to exclusive trigger hadron p(T) ranges. 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.
