| Abstract: | The acollinearity of hadrons belonging to back-to-back jets in e+e? annihilation is investigated in the framework of QCD. The approach is based on the evolution equations for fragmentation functions, and it takes into account the non-perturbative intrinsic transverse momentum. The results are compared with recent data, and satisfactory agreement is obtained. |
