Role of scalar mesons in the beam asymmetry of $p\bar{p}$ and $\Lambda \bar{\Lambda }$ photoproduction at JLab

We suggest a description of the beam asymmetry in $p\bar{p}$ and $\Lambda \bar{\Lambda }$ photoproduction off the proton $\vec{\gamma }+p\to p\bar{p}+p$ and $\vec{\gamma }+p\to \Lambda \bar{\Lambda }+p$, takes into accou…
