Rapidity and transverse-momentum distribution of produced particles in e+e- annihilation and pp collision at high energy

The simplest compound picture of the one-dimensional string model and the fireball model is used to describe the rapidity and squared transverse-momentum distributions of produced particles in e(+)e(-) annihilation and pp collision at high energy. The calculated results are in agreement with the experimental data. It is shown that, in the rest frame of the fireball, the particles presented isotropic emission and the three components of the momentum can be regarded as Gaussian type having the same width.
