“…The description of the elementary e + p → e + K + + Λ process involving an isolated proton at rest has been obtained from the isobar model [13,14], in which the hadron current is derived from an effective Lagrangian comprising baryon and meson fields. Different implementations of this model are characterized by the intermediate states appearing in processes featuring the excitation of resonances [15][16][17].…”

Experimental studies of hypernuclear dynamics, besides being essential for the understanding of strong interactions in the strange sector, have important astrophysical implications. The observation of neutron stars with masses exceeding two solar masses poses a serious challenge to the models of hyperon dynamics in dense nuclear matter, many of which predict a maximum mass incompatible with the data. In this paper, it is argued that valuable new insight can be gained from the forthcoming extension of the experimental studies of kaon electro production from nuclei to include the 208Pb(e,e′K+)Λ208Tl process. A comprehensive framework for the description of kaon electro production, based on factorization of the nuclear cross section and the formalism of the nuclear many-body theory, is outlined. This approach highlights the connection between the kaon production and proton knockout reactions, which will allow us to exploit the available 208Pb(e,e′p)207Tl data to achieve a largely model-independent analysis of the measured cross section.

The E01-011 experiment at Jefferson Laboratory (JLab) studied light-to-medium mass Λ Until recently, hypernuclei were studied at accelerator facilities with intense π + and K -meson beams. The poor quality of these beams limited the resolution of the hypernuclear excitation energy spectra to about 1.5 MeV (FWHM). This resolution is not sufficient for resolving the rich structure observed in the excitation spectra. By using a high quality electron beam and employing a new high resolution spectrometer system, this study aims to improve the resolution to a few hundred keV with an absolute precision of about 100 keV for excitation energies. hypernuclei via the ( 1)AIn this work the high-resolution excitation spectra of In conclusion, the discrepancies found in this study will provide valuable input for the further development of theoretical models.v

Λ hypernuclear spectroscopy by the (e, e ′ K + ) reaction is a powerful tool to investigate ΛN interaction because this reaction excites various states up to deep inside of hypernucleus and sub-MeV resolution can be achieved thanks to the high quality primary electron beam from CEBAF at JLab. The second generation hypernuclear spectroscopy at JLab Hall C, E01-011 experiment, was successfully performed in the summer of 2005 introducing High resolution Kaon Spectrometer (HKS) and a new configuration for scattered electron spectrometer. These unique techniques significantly improved both energy resolution and hypernuclear tagging efficiency, and we succeeded to study various hypernuclei including 12 Λ B and 28 Λ Al with high resolution and sufficient statistics for the first time by this reaction.
