  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.
