N2 - In 2018, the E12-17-003 experiment was conducted at the Thomas Jefferson National Accelerator Facility (JLab) to explore the possible existence of an nnΛ state in the reconstructed missing mass distribution from a tritium gas target [K. N. Suzuki, Prog. Theor. Exp. Phys. 2022, 013D01 (2022)2050-391110.1093/ptep/ptab158; B. Pandey, Phys. Rev. C 105, L051001 (2022)2469-998510.1103/PhysRevC.105.L051001]. As part of this investigation, data were also collected using a gaseous hydrogen target, not only for a precise absolute mass scale calibration but also for the study of Λ/ς0 electroproduction. This dataset was acquired at Q2≃0.5 (GeV/c)2, W=2.14 GeV, and θγKc.m.≃8°. It covers forward angles where photoproduction data are scarce and a low-Q2 region that is of interest for hypernuclear experiments. On the other hand, this kinematic region is at a slightly higher Q2 than previous hypernuclear experiments, thus providing crucial information for understanding the Q2 dependence of the differential cross sections for Λ/ς0 hyperon electroproduction. This paper reports on the Q2 dependence of the differential cross section for the e+p→e′+K++Λ/ς0 reaction at 0.2-0.8 (GeV/c)2, and provides comparisons with the currently available theoretical models.
