Using and Constraining Nonforward Parton Distributions (Deeply Virtual Neutrino Scattering in Cosmic Rays and Light Dark Matter Searches)

Abstract

We overview the construction of Nonforward Parton Distributions (NPD) in Deeply Virtual Compton Scattering (DVCS). Then we turn to the analysis of similar constructs in the weak sector (electroweak NPD's). We argue in favour of a possible use of electroweak DVCS (EWDVCS) as a rare process for the study of neutrinos in cosmic rays and for light dark matter detection in underground experiments
