Description
We have been performed a high resolution hypernuclear mass spectroscopy measurement by the $(e,e’K^{+})$ reaction at the Thomas Jefferson National Accelerator Facility (JLab). The differential cross section for the $\Lambda/\Sigma^0$ electroproduction is fundamental information to estimate yields of hypernuclei in experiments. Although $\Lambda/\Sigma^0$ photoproduction has been studied well by CLAS, SAPHIR, LEPS and so on, $\Lambda/\Sigma^0$ electroproduction data is very limited quantitatively and qualitatively.
We performed the E12-17-003 experiment in JLab Hall-A in 2018. In this experiment, we have taken data on a gas hydrogen target, which is important not only for an absolute mass scale calibration, but for the study of $\Lambda/\Sigma^0$ electroproduction. In this talk, I will report the results of the differential cross section for the $p(e,e'K^{+})\Lambda/\Sigma^0$ reaction at $Q^2\sim0.5$ $(\mathrm{GeV}/c)^2$.
