This proposal is an extension request of the partially approved proposal of JLab E01-011. The experimental goal of the E01-011 experiment was to prove the effectiveness of (e, e'K +) hypernuclear spectroscopy by employing the " tilt method " for the electron arm and by installing a new high-resolution kaon spectrometer (HKS) for the kaon arm. It was(More)
Contributions of the direct quark mechanism are studied in the nonmesonic weak decays of light hypernuclei. The ΛN → N N transition is described by the one pion exchange mechanism and the direct quark mechanism, induced by the four-quark vertices in the effective weak Hamil-tonian. By employing a realistic wave function of the Λ inside the hypernuclei,(More)

In order to understand baryon-baryon interactions under flavored SU(3), one must investigate the interaction between nucleons and hyperons, which can be accessed so far mainly by studying hypernuclei. Since hyperons are expected to be one of the main ingredients of neutron dense matter such as neutron stars, understanding the interaction including hyperons(More)
We propose to use high precision monochromatic -'s from the unique two body mesonic weak decay of hypernuclei to investigate light -hypernuclei with a variety of (Z, A) combination through identification of hyperfragments from strongly produced hypernuclear continuum (quasi-free production) in (e, K +) electro-production. Technically, the combination of(More)
