Abstract
Excited vector mesons, some of which are predicted to include gluonic excitation in their wave functions, and certain classes of axial vector mesons, some of which are implicated in the decay of spin-exotic mesons, decay dominantly to vector-pseudoscalar final states. In particular, the axial vector b1(1235) decays dominantly to ωπ, and is produced copiously at the GlueX experiment. It provides a testing ground to explore strategies for amplitude analysis of further vectorpseudoscalar channels where the intermediate resonances may be harder to isolate. The formalism for amplitude analysis of b−1 production via charge exchange with a recoiling Δ++ is presented here, and compared with the proton recoil case. A strategy for a systematic analysis of reactions involving Δ++ recoil is outlined.
