| Abstract: | We study the region of small transverse momenta in the dynamics of the gluon-gluon annihilation channel. This is done by evaluating the gluon form factor at the single non-leading infrared and collinear logarithmic accuracy to all orders in αs. An explicit expression for the gluon form factor is obtained. The results are compared with those for the analogous quark case. |
