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, $〈{{k}_{\ensuremath{\perp}}}^{2}〉$. For large ${k}_{\ensuremath{\perp}}$, our proposed approximation gives an exponential damping in ${k}_{\ensuremath{\perp}}$ which is independent of the coupling constant. The discontinuous nature of the four-momentum distribution is examined to make comparison with perturbation theory.
