Title: Wide Angle Compton Scattering within the SCET framework

Abstract: 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. 

Best regards,
