Talk

No published data for $\Lambda n$ scattering exist. A relativistic heavy-ion experiment [1] has suggested that a $\Lambda nn$ bound state has been seen. If that were the case, our knowledge of the $nn$ interaction would permit one to use that $\Lambda nn$ bound state energy to generate strong constraints on the $\Lambda n$ interaction. JLab would be an ideal facility to obtain such data...

86. Light single- and double-lambda hypernuclei in pionless effective field theory

Strange systems and hypernuclei

Talk

We present the first comprehensive study of pionless effective field theory to A$\le$6 single and double $\Lambda$ hypernuclei.
The theory, which is fitted entirely from available experimental data, solves the longstanding overbinding problem of the $^5_\Lambda$He hypernucleus and allows to predict the existence of bound states in single- and double-$\Lambda$ neutral Hypernuclei still under...

75. Study of the Hyperon-nucleon interaction using the CLAS detector

Strange systems and hypernuclei

Talk

Obtaining a detailed understanding of the physics of hyperons allow us to improve our basic understanding of the strong force, which is currently based on nucleons, and allow a deeper understanding of matter in neutron stars. The difficulty in obtaining a high-quality data set of hyperon-nucleon scattering lies with experimental difficulties in obtaining hyperon beams or targets. Here I will...
