Description
I present the results from the amplitude analysis of the photoproduction of $\pi^{-}\Delta^{++}$. The GlueX data on the spin-density matrix elements of this process have been used to extract the phase relationship between the helicity amplitudes in a model independent way. Using the crossing relations and the principle of duality, the cross-channel residues and from them, the couplings for various meson exchanges have also been extracted.
