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

All interested persons are cordially invited to attend.
*Guest parking is available near the ODU Physics Department.*
