Two-body LambdaN-SigmaN coupling resolves overbinding in Lambda-He5 but causes underbinding in four-body systems. Explicit Lambda-Sigma coupling, a three-body force, corrects this underbinding in Lambda-H4 and Lambda-He4 systems.

Area of Science:

  • Nuclear Physics
  • Hypernuclear Physics

Background:

  • Two-body LambdaN-SigmaN coupling addresses overbinding in Lambda-He5.
  • This coupling leads to underbinding in four-body systems.

Purpose of the Study:

  • Investigate the role of Lambda-Sigma coupling as a three-body force.
  • Explain the underbinding observed in four-body hypernuclei.
  • Analyze the 0(+)-1(+) splitting in Lambda-H4 and Lambda-He4.

Main Methods:

  • Utilizing the Nijmegen soft-core potential.
  • Introducing explicit Lambda-Sigma coupling, equivalent to a LambdaNN three-body force.
  • Analyzing spin-spin interactions and Lambda-Sigma coupling effects.

Main Results:

  • Lambda-Sigma coupling successfully overcomes underbinding in four-body systems.

  • This three-body force is significant in the 0(+) states of Lambda-H4 and Lambda-He4.
  • The 0(+)-1(+) splitting is attributed to both LambdaN spin-spin interaction and Lambda-Sigma coupling.

    • Conclusions:

    • The Lambda-Sigma coupling is crucial for accurately describing the binding energies of light hypernuclei.
    • The proposed three-body force model successfully explains experimental observations in Lambda-H4 and Lambda-He4.
    • Refined potential models are essential for understanding hypernuclear structure.
