Binding energy of a Λ particle in nuclear matter with tensor Λ N interaction

The tensor component in the modified Harndon and Tang ΛN potential (MHT) is found to increase the binding of a Λ particle in nuclear matter by about 5 MeV. A comparison with a pure central ΛN potential of similar low energy Λp scattering parameters as the MHT potential gives about 2 MeV for the tensor suppression effect.

Matrix elements of the lambda-nucleon potential from phase shifts

Experimental ΛN phase shifts are used to deduce matrix elements of the ΛN potential in a harmonic oscillator basis. An inconsistency between these matrix elements and experimental Λ separation energies for light hypernuclei is noted.
