WASA-FRS HypHI experiment at GSI for studying light hypernuclei

From January till March 2022, the WASA-FRS HypHI experiment performed a precise measurement of the hypertriton and the 4 Λ H hypernucleus lifetime at GSI. The data collected should also confirm whether or not the nn Λ bound state can exist. The experiment were carried out with the WASA central detec...

Description
Summary:From January till March 2022, the WASA-FRS HypHI experiment performed a precise measurement of the hypertriton and the 4 Λ H hypernucleus lifetime at GSI. The data collected should also confirm whether or not the nn Λ bound state can exist. The experiment were carried out with the WASA central detector with a complex of additional dedicated detectors mounted together at the mid-focal plane of the high-momentum-resolution forward spectrometer, the so-called fragment separator FRS. Hypernuclei of interest were produced by induced reactions of 6 Li projectiles at 1.96 A GeV on a diamond target with a thickness of 9.87 g/cm 2 . Negatively charged π mesons from two-body decays of the hypernuclei of interest were measured by theWASA and the other detectors, and the residual nuclei after the π − decay were measured by the FRS with a momentum resolving power of 10 4 .
