Structure of light \Xi hypernuclei and Hyperon-Hyperon interaction
=Abstract=
Recently, \Xi hypernucleus, 14N-\Xi hyperuclei, were observed as a bound state, which was the first bound \Xi hypernucleus. From this data, we found that \Xi- nucleus potential should be attractive.
As next step, it is important to know which contribution of \Xi-N interaction should be attractive or repulsive. To study these contributions, it is suited to study light $\Xi$ hypernuclei. In this seminar, I will report some \Xi hypernuclei from the view point of the few-body problem.
