<p><b>Power Corrections to TMD Factorization</b></p>
To study transverse momentum distribution of particle production
in hadron-hadron <br>
collision one can use transverse momentum dependent (TMD)
factorization approach. <br>
The TMD factorization is valid in the limit of infinitely small
transverse momentum, <br>
i.e. when the transverse momentum of a produced particle is much
smaller than its <br>
invariant mass. To apply the TMD factorization in the region of
moderate transverse <br>
momentum one has to include power corrections. I will discuss how
one can calculate <br>
power corrections to TMD factorization through the solution of
equations of motion <br>
in background fields of colliding hadrons.<br>
