Description

The E12-17-003 Experiment was carried out successfully at Jefferson lab in 2018 using a pressurized tritium target. By utilizing the Hall A high-resolution spectrometers and the 3H(e,eK+)Λnn reaction, enhancements which may correspond to the possible Λnn resonance and a pair of ΣNN sate were observed with an energy resolution of 1.21 MeV (σ), although the greater statistics are required to make the definite identifications. The experimentally measured Λnn state can provide unique constraints in determining the Λn interaction for which no scattering data exist. In addition, although bound A = 3 and 4 Σ hypernuclei have been predicted, only an A = 4 Σ hypernucleus (Σ4He) was experimentally observed using the (K,π) reaction on a 4He target. The bound ΣNN state is possibly a Σ0nn state, although this has to be confirmed by future experiments. This presentation will give a description of this experiment, its analysis, and its results.
