Measurements of the photon induced production of $Lambda$ in the $^2$H$({gamma},{Lambda})$X process at threshold energies

An experiment was carried out with the NKS2+ in 2010 at the Research Center for Electron Photon Science (ELPH), in which tagged photon beams in the range of 0.8 $le$ $E_{gamma}$ $le$ 1.1 GeV were impinged on a liquid $^2$H target positioned at the center of the NKS2+. The produced $Lambda$ was subsequently detected by the $p{pi^{-}}$ decay channel. Integrated cross sections of the $^2$H$({gamma},{Lambda})$X in the angular region of 0.9 $le$ $cos{theta}_{Lambda}^{LAB}$ $le$ 1.0 was derived and compared with preceding experimental results of the NKS2 collaboration. In addition, the momentum spectra for two photon energy regions were also procured. The ${Lambda}$ angle dependent cross sections as a function of the scattering angle in the laboratory system was additionally deduced. We present the latest results on the excitation function of ${Lambda}$ photoproduction, the momentum distributions, angular distributions, and polarization.
