Abstract
The transverse-momentum distribution is studied using the Bloch-Nordsieck method. An approximate analytic form for the above distribution is found, which maintains the normalization as well as reproduces the exact result for the average (squared) transverse momentum, . For large , our proposed approximation gives an exponential damping in which is independent of the coupling constant. The discontinuous nature of the four-momentum distribution is examined to make comparison with perturbation theory.
