Baryon-Baryon coupling in hypernuclei
- and others
Baryon-baryon coupling such as {Lambda}N-{Sigma}N in {Lambda} hypernuclei and {Lambda}{Lambda}-{Xi}N in {Lambda}{Lambda} hypernuclei produce novel physics not observed in conventional nonstrange nuclei. This is especially evident in few-body systems. To illustrate this, a comparison of S = {minus}1 and S = 0 baryon-separation energies is made. The role of {Lambda}N-{Sigma}N coupling suppression in the A = 4 {Lambda} hypernuclei due to Pauli blocking is reviewed. The analysis is extended to S = {minus}2 systems. Measurement of the {sub {Lambda}{Lambda}}{sup 4}H or {sub {Lambda}{Lambda}}{sup 5}He {Lambda}{Lambda} separation energy is proposed as a means to investigate the full {Lambda}{Lambda} and {Xi}N interaction.
