Analytic Properties of DPE Amplitudes or Collinear Factorisation for Central Exclusive Production
Analytic and crossing properties of amplitudes of the central exclusive production (CEP) are considered using the formalism of collinear Generalised Parton Distributions (GPDs). The analytic continuation from unphysical region is considered which leads to the finite expression. The natural interpret...
