“…Motivation of our current work is to study CSB with A=4 mirror  hypernuclei. Since 1960s, emulsion experiments reported B  of 4  H and 4  He in ground state (0 + ) [1][2][3]. The combined results for B  (0 + ) of 4  H and 4  He were reported by M. Juric et al [4] to be 2.04 ± 0.04 MeV and 2.39 ± 0.03 MeV, respectively.…”

In recent years, the high-precision technique of decay-pion spectroscopy at the Mainz Microtron (MAMI), using high-resolution magnetic spectrometers, contributed to the accurate determination of the Λ binding energy of 4 Λ H. For the lightest hypernucleus, the hypertriton, the binding energy is known only from measurements carried out with nuclear emulsions. An account is given on the potential of observing the hypertriton with decay-pion spectroscopy from fragmentation of light target nuclei. Statistical decay calculations suggest that lithium is the optimal target material to observe hypertriton decays under relative clean conditions with only few other light hyperfragments being produced. Finally, a high-precision measurement of the hypertriton mass at MAMI is proposed.

“…The statistical uncertainty for the binding energies in light hypernuclei with the emulsion method ranged from a minimum of 20 keV for the most abundant hypernuclei 5 Λ He to more than 700 keV for 8 Λ He [2][3][4]. Systematic errors in the emulsion data are not shown, but D.H. Davis assumed errors of the order of 50 keV [5].…”

Abstract. Negatively charged pions from two-body decays of stopped 4 Λ H hypernuclei were studied in 2012 at the Mainz Microtron MAMI, Germany. The momenta of the decay-pions were measured with unprecedented precision by using high-resolution magnetic spectrometers. A challenge of the experiment was the tagging of kaons from associated K + Λ production off a Be target at very forward angles. In the year 2014, this experiment was continued with a better control of the systematic uncertainties, with better suppression of coincident and random background, improved particle identification, and with higher luminosities. Another key point of the progress was the improvement in the absolute momentum calibration of the magnetic spectrometers.
