We investigate the properties of the hidden charm pentaquark-like resonances first observed by LHCb in 2015, by measuring the polarization transfer KLL between the incident photon and the outgoing proton in the exclusive photoproduction of J/psi near threshold. We present a first estimate of the sensitivity of this observable to the pentaquark photocouplings and hadronic branching ratios, and extend our predictions to the case of initial state helicity correlation ALL, using a polarized target. These results serve as a benchmark for the SBS experiment at Jefferson Lab, which proposes to measure for the first time the helicity correlations ALL and KLL in J/psi exclusive photoproduction, in order to determine the pentaquark photocouplings and branching ratios.

Faddeev equations for the $J/\psi\,NN$ and $\phi\,NN$ three-body systems in momentum space
A momentum-space Faddeev calculation with Malfliet-Tjon and HAL QCD potentials predicts phi-nucleon-nucleon bound states and no J/psi-nucleon-nucleon bound state.
