Differential cross section of the $p(e,e'K^{+})\Lambda/\Sigma^{0}$ reaction at $Q^{2}\simeq0.5$ [(GeV/$c$)$^{2}$]*

We have performed high resolution mass spectroscopy of hypernuclei with the $(e,e'K^{+})$ reaction using the high intensity electron beam of CEBAF at Thomas Jefferson National Accelerator Facility (JLab). Although hyperons electroproduction elementary process at low $Q^2$ is indispensable for the hypernuclear research, both quality and quantity of data in forward angles are far from satisfactory. In the $(e,e'K^{+})$ reaction, protons are converted into hyperons, so this makes it possible to measure the cross section of the $p(e,e'K^{+})\Lambda/\Sigma^0$ reaction on a gas H$_{2}$ target. We deduced the differential cross section of the $p(e,e'K^{+})\Lambda/\Sigma^0$ reaction with calibration data of the latest hypernuclear experiment (JLab E12-17-003). These data were collected at Experimental Hall A using two high-resolution magnetic spectrometers, HRS's, and we measured the momentum vectors of the kaons and scattered electrons. They correspond to data sets of $W\simeq3.0$ [GeV] and $Q^2\simeq0.5$ [(GeV/$c$)$^{2}$]. In this presentation, I will report the result of the analysis for the $p(e,e'K^{+})\Lambda/\Sigma^{0}$ reaction.
