| Title | High-resolution hypernuclear decay pion spectroscopy at MAMI and future | ||||
| Abstract | Hypernuclear decay pion spectroscopy was established in 2012 at MAMI as a mass spectroscopy method for light hypernuclei. A monochromatic pion peak from 4-Lambda-H was successfully observed, and the Lambda binding energy was determined to be B_Lambda = 2.157 ± 0.005 (stat.) ± 0.077 (syst.) MeV in the 2014 run. In 2022, an upgrade experiment for 3-Lambda-H spectroscopy was conducted using a newly developed Li target. The absolute electron beam energy will be measured by the synchrotron radiation interferometry, which will be applied with the spectrometer calibration to improve the systematic error. The decay pion spectroscopy is planned to be performed at JLab Hall-C, which would significantly increase the statistics thanks to the higher energy beam, the better K+ identification, and the faster data acquisition system. This experiment has been submitted as a Letter of Intent in JLab PAC51. The upgraded decay pion spectroscopy method is expected to provide new, accurate hypernuclear data | ||||
