Electroproduction of the Λ/Σ0 hyperons at ????2≃0.5 (GeV/????)2 at forward angles

Popis výsledku v původním jazyce

In 2018, the E12-17-003 experiment was conducted at the Thomas Jefferson National Accelerator Facility (JLab) to explore the possible existence of an ????⁢????⁢Λ state in the reconstructed missing mass distribution from a tritium gas target [K. N. Suzuki et al., Prog. Theor. Exp. Phys. 2022, 013D01 (2022), B. Pandey et al., Phys. Rev. C 105, L051001 (2022)]. 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 ????2≃0.5 (GeV/????)2, ????=2.14 GeV, and ????c.m.n????⁢K≃8∘. It covers forward angles where photoproduction data are scarce and a low-????2 region that is of interest for hypernuclear experiments. On the other hand, this kinematic region is at a slightly higher ????2 than previous hypernuclear experiments, thus providing crucial information for understanding the ????2 dependence of the differential cross sections for Λ/Σ0 hyperon electroproduction. This paper reports on the ????2 dependence of the differential cross section for the ????+????→????′+????++Λ/Σ0 reaction at 0.2–0.8 (GeV/????)2, and provides comparisons with the currently available theoretical models.
