Query: Perturbative QCD Approach to Multiparticle Production   In this review we discuss the analytical perturbative approach, based on
perturbative QCD and Local Parton Hadron Duality (LPHD), and its application to
multiparticle production in jets in the semisoft region. Analytical formulae
are presented for various observables within the accuracy of the Modified
Leading Logarithmic Approximation (MLLA), i.e. with terms of relative order
$\sqrt{\alpha_s}$ taken into account systematically, and in some cases with
even higher accuracy. These predictions are confronted with existing
experimental data. Many details of the perturbative approach to multiple
hadroproduction have been consolidated in recent years, and the overall picture
is remarkably healthy. The prospects of future studies of the semisoft jet
physics are also discussed.
