<div>The factorization theorem for WACS amplitude is derived within
the Soft Collinear Effective Theory framework. <br>
We obtained that the leading contribution to the amplitude is
described by a sum of the hard- and soft-spectator<br>
contributions. The hard-spectator part reproduces the well known
pQCD factorization result. The soft-spectator <br>
contribution describes the so-called soft-overlap mechanism and
has not yet been considered before in the <br>
factorization framework. </div>
<div> </div>
<div>We performed the leading and next-to-leading calculation of the
hard kernel for the soft-spectator contribution <br>
and used obtained results for a phenomenological analysis of
existing data. </div>
