| dc.description | The Kwiecinski evolution of unintegrated parton distributions (UPDs) in the transverse-coordinate space is analyzed with the help of the Mellin transform. Numerical results are presented for the unintegrated pion distributions with a simple valence-like initial condition at the low scale, which follows from chiral large-Nc quark models. The effect of spreading of UPDs in the transverse momentum with the increasing scale is confirmed, with <kT^2> growing asymptotically as Q^2 alpha(Q^2). Formal aspects of the equations, such as the limits of UPDs at x -> 0, x -> 1, and at low and large b, are straightforward to obtain with our method. | |
