Novel Pion Electroproduction Low-Energy Theorems

Abstract

We present novel low--energy theorems for the P--wave multipoles $2M_{1+}+M_{1-}$, $M_{1+}-M_{1-}$, $E_{1+}$ and $L_{1\pm }$ for neutral pion electroproduction off protons. These should be very useful for the analysis of existing or future threshold data.
