HKS experiment status (E01-011 Preparation) Osamu Hashimoto Tohoku University Jlab Hall C Meeting January 9, 2002
Current issues of hypernuclear physics • A new degree of freedom • can examine deeply bound states • baryon structure in nuclear medium • New nuclear structure with strangeness • nucleus with a new quantum number • electromagnetic properties • Hyperon-nucleon, hyperon-hyperon interaction • Hyperon scattering and hypernuclear structure • S=-2 system and beyond high quality(high resolution & high statistics) spectroscopy plays a significant role Reaction spectroscopy : From MeV to sub-MeV resolution g-ray spectroscopy : Larger detection efficiency
The (e,e’K+) reaction spectroscopy • New generation hypernuclear spectroscopy
12C(p+,K+)12LC spectra by the SKS spectrometer at KEK 12 GeV PS 2 MeV(FWHM) 1.45 MeV(FWHM) E369 E336
