### Single-energy partial wave analysis for π0 photoproduction on the proton with fixed-t analyticity imposed

DOI:https://doi.org/10.1103/PhysRevC.100.055203

Abstract

High-precision data of the $\gamma p \rightarrow \pi^0p$ reaction from its threshold up to W=1.9GeV have been used in order to perform a single-energy partial-wave analysis with minimal model dependence. Continuity in energy was achieved by imposing constraints from fixed-t analyticity in an iterative procedure. Reaction models were only used as starting point in the very first iteration. We demonstrate that, with this procedure, partial-wave amplitudes can be obtained which show only a minimal dependence on the initial model assumptions.
