@article{Dey2014DataAT, title={Data analysis techniques, differential cross sections, and spin density matrix elements for the reaction $\gamma$p→$\phi$p}, author={Biplab Dey and Christopher Meyer and Matthew Bellis and M. Williams}, journal={Physical Review C}, year={2014}, volume={89}, pages={055208} }
High-statistics measurements of differential cross sections and spin density matrix elements for the reaction γ p → ϕ p have been made using the CLAS detector at Jefferson Lab. We cover center-of-mass energies ( s ) from 1.97 to 2.84 GeV, with an extensive coverage in the ϕ production angle. The high statistics of the data sample made it necessary to carefully account for the interplay between the ϕ natural lineshape and effects of the detector resolution, that are found to be comparable in…

The measurement results support strong constructive interference when K^{+}K^{-} pairs are observed at forward angles but destructive interference for proton emission at forward angle, and suggest possible exotic structures such as a hidden-strangeness pentaquark state, a new Pomeron exchange, or rescattering processes via other hyperon states.
