Observation of $\gamma p\to \Lambda \bar{\Lambda }p$ with GlueX at Jefferson Lab

Reinhard Schumacher, Hao Li

For the first time, baryon-antibaryon photoproduction in the reaction $\gamma p\to \Lambda \bar{\Lambda }p$ has been observed at photon energies from threshold near 4.9 GeV to 11.6 GeV. The measuremen…
