On the stability of Lambda(1405) matter
Original language description
A hypothesis of absolutely stable strange hadronic matter composed of Lambda(1405) baryons, here denoted Lambda(star), is tested within many-body calculations performed using the Relativistic Mean-Field approach. In our calculations, we employed the Lambda(star)Lambda(star) interaction compatible with the Lambda(star)Lambda(star) binding energy Lambda(star)Lambda(star) = 40 MeV given by the phenomenological energy-independent K- N interaction model by Yamazaki and Akaishi (YA). We found that the binding energy per Lambda(star), as well as the central density in Lambda(star) many-body systems saturates for mass number A (inequality) 120, leaving Lambda(star) 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.
