"Wide Angle Compton Scattering within the SCET framework"

Dr. Nikolai Kivel
Helmholtz Institute Mainz
Mainz, Germany


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.
