Interactions of Hyperons and Hypernuclei

Contributor: G. Franklin.

The conclusions reached through the talks and afternoon discussions on hypernuclei and hyperons which are notable or unique to this workshop are:

1.

From both experimental and theoretical considerations, further studies of $\Sigma$-hypernuclei should not be a priority at existing facilities.

2.

Better measurements of the $\Lambda N$ phase shifts are crucial to understanding the dense hadronic systems that occur in stellar environments.

3.

The study of hyperonic atoms continues to provide valuable insight into the interaction between hyperons and nucleons.

4.

The $\Xi^0$ mass is the poorest known of the hyperons. A more precise measurement will be a valuable discriminator between theoretical treatments.

Priorities for this area of research, given in no particular order:

1.

Maintain the AGS for strangeness research, both rare K-decays and the hypernuclear program.

2.

Perform finite nucleus calculations of hypernuclei.

3.

Attempt to measure the $p n \rightarrow p \Lambda$ weak cross section and spin dependent observables.

4.

Determine the spin-dependence of the $\Lambda N$ interaction.

5.

Determine the ground state binding of a $\Lambda\Lambda$hypernuclei.

6.

Look for poles in the $\Lambda\Lambda$ scattering amplitude.

7.

Perform precision tests of the $\Delta I =1/2$ rule in the non-mesonic decay of hypernuclei.

8.

Extract YN phase shifts.

9.

Produce and study $\Xi$-nucleus atoms, (see [21])
