    The transverse momentum distribution of (anti)quarks created in the chromo-electric field of an infinitely long hadronic flux tube is derived. The effects of the finite radius of the hadronic strings on their fragmentation are studied simulating e+e- annihilation events in the framework of a dynamical string model that contains two parameters: the string tension κ=0.89 GeV/fm (determined by the Regge slope), and the radius of the string. It is shown that a string radius of about 0.5 fm allows to describe successfully both the width of the transverse momentum distribution in the low-pT region and the multiplicities.
