The Lambda Lambda interaction and the reaction Xi plus deuteron goes to neutron plus Lambda plus Lambda{dagger}

PDF Version Also Available for Download.

Description

Interest in the {Lambda}{Lambda} interaction is partly due to the presence of quark-model predictions for an S = {minus}2 dibaryon, and partly to the interest in the role of the coupling between the {Lambda}{Lambda} and {Xi}{Nu} channels in {Lambda}{Lambda} hypernuclei. This latter effect is expected to be substantially more important than the coupling of the {Nu}{Nu} to the {Nu}{Delta} channel in the S = 0 sector, since the difference in threshold between the {Lambda}{Lambda} and {Xi}{Nu} is only {approx}25 MeV. In the absence of any direct measurement of the {Lambda}{Lambda} amplitude, one must resort to either {Lambda}{Lambda} hypernuclei, or to ... continued below

Description

Interest in the {Lambda}{Lambda} interaction is partly due to the presence of quark-model predictions for an S = {minus}2 dibaryon, and partly to the interest in the role of the coupling between the {Lambda}{Lambda} and {Xi}{Nu} channels in {Lambda}{Lambda} hypernuclei. This latter effect is expected to be substantially more important than the coupling of the {Nu}{Nu} to the {Nu}{Delta} channel in the S = 0 sector, since the difference in threshold between the {Lambda}{Lambda} and {Xi}{Nu} is only {approx}25 MeV. In the absence of any direct measurement of the {Lambda}{Lambda} amplitude, one must resort to either {Lambda}{Lambda} hypernuclei, or to a reaction with a {Lambda}{Lambda} final-state interaction to determine the {Upsilon}{Upsilon} interaction. In this report the authors present results of a theoretical study of the hypernucleus {sub {Lambda}{Lambda}}{sup 6}He and the reaction {Xi}d {r_arrow} n{Lambda}{Lambda} whereby they examine the sensitivity of the calculations to details of the {Lambda}{Lambda} potential, and the coupling between the {Lambda}{Lambda} and the {Xi}{Nu} channels.
