On the stability of Λ(1405) matter
Original language description
A hypothesis of absolutely stable strange hadronic matter composed of Λ(1405) baryons, here denoted Λ*, is tested within many-body calculations performed using the Relativistic Mean-Field approach. In our calculations, we employed the Λ*Λ* interaction compatible with the Λ*Λ* binding energy BΛ*Λ* = 40 MeV given by the phenomenological energy-independent K N interaction model by Yamazaki and Akaishi (YA). We found that the binding energy per Λ*, as well as the central density in Λ* many-body systems saturates for mass number A >= 120, leaving Λ* aggregates highly unstable against strong interaction decay. Moreover, we confronted the YA interaction model with kaonic atom data and found that it fails to reproduce the K- single-nucleon absorption fractions at rest from bubble chamber experiments.
