Abstract

We discuss application of formalism of small- x effective action for reggeized gluons (Lipatov’s effective action), [1, 2, 3], for the calculation of classic al gluon field of relativistic color charge. The equations of motion with the reggeon fields are solved in L O and NLO approximations and the LO results are compared to the calculations performed in the CGC framework. It is demonstrated that the CGC results for the classical field are reproduced in our calculations.
