The limit $\xi \rightarrow 0$ of the GPD $\widetilde{E}$.
ORAL
Abstract
The GPD $\widetilde{E}$ integrates to the pseudoscalar form factor of the nucleon, $g_P$ which, due to the spontaneously broken chiral symmetry, is dominated by the contribution of a pion pole at low momentum transfer squared, $t$. The GPD $\widetilde{E}$ , allow us, therefore, to study the pseudoscalar content of the nucleon at the partonic level. In particular, we discuss the limit $\xi \rightarrow 0$ of the skewness parameter.
