Description
We rivisit Touschek’s resummation procedure for QED and highlight the
possibility of zero momentum modes, insofar neglected in the passage from
the discrete to the continuum, but possible under special boundary conditions.
We shows how to separate and extract the zero momentum mode in soft
photon emission both in the relativistic and non-relativist limit. An ansatz is presented to extend the procedure to QCD, and the possibility that this mode manifest itself in the forward peak in elastic pp scattering. A preliminary phenomenology is discussed.
