Abstract
The electroproduction of selected p- and sd-shell hypernuclei was studied within a many-body approach using realistic interactions between the constituent baryons. The cross sections were computed in the distortedwave impulse approximation using two elementary amplitudes for the electroproduction of the Lambda hyperon.
The structure of the hypernuclei was investigated within the framework of the self-consistent Lambda-nucleon Tamm-Dancoff approach and its extension known as the Lambda-nucleon equation of motion phonon method. Use was made of the NNLOsat chiral potential plus the effective Nijmegen-FYN interaction.
The method was first implemented on light nuclei for studying the available experimental data and establishing a relation to other approaches. After this proof test, it was adopted for predicting the electroproduction cross section of the hypernuclei K-40(Lambda) and K-48(Lambda) in view of the E12-15-008 experiment in preparation at JLab.
On the grounds of these predictions, appreciable effects on the spectra are expected to be induced by the YN interaction.
