HKS experiment status (E01-011 Preparation)
Osamu HashimotoTohoku University
Jlab Hall C MeetingJanuary 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-ray spectroscopy : Larger detection efficiency
The (e,e’K+) reaction spectroscopy
• New generation hypernuclear spectroscopy
