Importance of Baryon-baryon Coupling in Hypernuclei
نویسنده
چکیده
The ΛN − ΣN coupling in Λ–hypernuclei and ΛΛ − ΞN coupling in ΛΛ– hypernuclei produce novel physics not observed in the conventional, nonstrange sector. Effects of Λ ↔ Σ conversion in ΛH are reviewed. The role of ΛN − ΣN coupling suppression in the A = 4, 5 Λ–hypernuclei due to Pauli blocking is highlighted, and the implications for the structure of 10 ΛB are explored. Suppression of ΛΛ − ΞN conversion in 6 ΛΛHe is hypothesized as the reason that the < VΛΛ > matrix element is small. Measurement of 4 ΛΛH is proposed to investigate the full ΛΛ−ΞN interaction. The implication for ΛΛ analog states is discussed.

What Does the Free Space LL Interaction Predict for LL Hypernuclei?
Data on LL hypernuclei provide a unique method to learn details about the strangeness S 22 sector of the baryon-baryon interaction. From the free space Bonn-Jülich potentials, determined from data on baryon-baryon scattering in the S 0,21 channels, we construct an interaction in the S 22 sector to describe the experimentally known LL hypernuclei. After including short-range (Jastrow) and RPA co...

متن کاملProductions of Double Hypernuclei with antiprotons at PANDA
One of the goals of hypernuclear physics is to study the properties of baryon-baryon interaction including the strangeness contribution. Double hypernuclei can provide information about the ΛΛ interaction in addition to the hyperon-hyperon and hyperon-nucleus one. A new technique for producing double hypernuclei using antiprotons is foreseen in the PANDA experiment at FAIR. Gamma ray spectrosco...
متن کاملS ep 1 99 7 1 The ΛΛ interaction and the reaction Ξ − + d → n + Λ + Λ ∗
Interest in the ΛΛ interaction is partly due to the presence of quark-model predictions for an S = −2 dibaryon [1], and partly to the interest in the role of the coupling between the ΛΛ and ΞN channels in ΛΛ hypernuclei [2]. This latter effect is expected to be substantially more important than the coupling of the NN to the N∆ channel in the S = 0 sector, since the difference in threshold betwe...
متن کامل4 ΛΛ bond energy from the Nijmegen potentials
The ΛΛ bond energy ∆B ΛΛ in ΛΛ hypernuclei is obtained from a G-matrix calculation which includes the coupling between the ΛΛ, ΞN and ΣΣ channels, as well as the effect of Pauli blocking to all orders. The Nijmegen NSC97e model is used as bare baryon-baryon interaction in the strangeness S = −2 sector. The ΛΛ-ΞN coupling increases substantially the bond energy with respect to the uncoupled ΛΛ c...
