Measurement of the generalized form factors near threshold via ${\gamma }^{\ast }p\to n{\pi }^{+}$ at high $Q^2$

Kijun Park, Ralf Gothe, Krishna Adhikari +144

We report the first extraction of the pion-nucleon multipoles near the production threshold for the $n{\pi }^{+}$ channel at relatively high momentum transfer ($Q^2$ up to 4.2 $\rm{GeV^2}…
