N2 - We suggest a description of the beam asymmetry in pp- and ΛΛ- photoproduction off the proton γ→+p→pp-+p and γ→+p→ΛΛ-+p, which takes into account the contribution of the scalar mesons f0(1370), f0(1500), and f0(1710). These scalars are considered as mixed states of a glueball and nonstrange and strange quarkonia in the framework based on the use of effective hadronic Lagrangians. Present results can be used to guide the possible search for this reaction by the GlueX Collaboration at JLab. Also, we did an estimate of contribution of heavier scalar meson states f0(2020), f0(2100), and f0(2200).
