Baryon anti-Baryon Photoproduction Cross Sections off the Proton Open
The GlueX experiment at Jefferson Lab has observed $p\bar{p}$ and, for the first time, $Λ\barΛ$ and $p\barΛ$ photoproduction from a proton target at photon energies up to 11.6 GeV. The angular distributions are forward peaked for all produ…

"Rosenbluth" separation of the $J/ψ$ near-threshold photoproduction -- an access to the gluon Gravitational Form Factors at high $t$ Open
We perform analysis of the near-threshold $J/ψ$ photoproduction data off the proton based on two theoretical approaches, GPD [1] and holographic [2], that represent the differential cross sections as powers of the skewness parameter with c…
