Description
The only recent η' photoproduction data off proton available in
literature are the differential and total cross sections published by
the CLAS and CB-ELSA-TAPS Collaborations. However, the wide information
about reaction cross sections are not sufficient to understand the role
of resonances involved in the process. Different theoretical works
stressed the importance to measure also polarization observables in
order to solve the ambiguities in the choice of the parameters used in
their models. We present the analysis of η' photoproduction off the
proton analysis, identifying the investigated meson by the
π+π-η,
π0π0η, and γγ decay modes by
using the GRAAL apparatus; and we show the preliminary GRAAL results on
the beam asymmetry Σ at beam energy of 1475 MeV.
