High \pt{} particle correlations in pp collisions at LHC/ALICE
  Two-particle correlation triggered by high-\pt{} particles allows us to study hard scattering phenomena when full jet reconstruction is challenging. An analysis of the first ALICE pp data where charged and neutral particles isolated or not are used as trigger particles is presented. The two-particle correlation between the trigger ($t$) and the associate ($a$) particles is studied as a function of the imbalance parameter \xe=-$\vec{p}_{T_{a}} \cdot \vec{p}_{T_{t}}/\mid \vec{p}_{T_{t}}\mid ^{2}$ and interpreted in terms of jet fragmentation function.
