Axial form factor of the nucleon at large momentum transfers

High Energy Physics - Phenomenology 2016-08-10 v2 Nuclear Experiment Nuclear Theory

Abstract

Motivated by the emerging possibilities to study threshold pion electroproduction at large momentum transfers at Jefferson Laboratory following the 12 GeV upgrade, we provide a short theory summary and an estimate of the nucleon axial form factor for large virtualities in the Q2=110 GeV2Q^2 = 1-10~\text{GeV}^2 range using next-to-leading order light-cone sum rules.
