Description
We will present on the recently approved Jefferson Lab experiment E12-16-007 which aims at measuring the $J/\psi$ photoproduction cross section as a function of proton momentum transfer variable $t$ and photon energy $E\gamma$ in the region of the recently discovered LHCb charmed pentaquark $P_{c}(4380)$ and $P_{c}(4450)$ resonances. The experiment will be performed using the Hall C HMS and SHMS spectrometers in coincidence to detect $e^{+} e^{-}$ di-lepton $J/\psi$ decay pair. The spectrometer settings were optimized to allow for the kinematics where the s-channel pentaquark signal, if it exists, is maximized compared to the $t$-channel background $J/\psi$ production. This measurement has the potential to confirm the existence of the s-channel charmed pentaquark with $5\sigma$ confidence down to $1.3\%$ coupling to the $J/\psi$ - p decay.
