“…In the case of the S = −2 systems, the (K − , K + ) reaction was used. The D6 beam line at BNL-AGS played a unique and important role in studies of the S = −2 systems by providing a high-quality and high-intensity K − beam at 1.8 GeV/c [58].…”

Since the shutdown of several old proton synchrotrons, which played a fundamental role in the second generation experiments in hypernuclear physics performed in Europe, USA and Japan, some new experimental setups aiming to achieve sub-MeV energy resolution have been operating for a long time. Over the last decade the hypernuclear physics community has been committed to carrying out several third generation experiments by exploiting the potential offered by new accelerators, such as a continuous electron beam machine and a ϕ-factory. Large data samples were collected on specific items thanks to dedicated facilities and experimental apparatuses. The attention was mainly focused on both high-resolution spectroscopy and the decay mode study of single Λ-hypernuclei. Nowadays this phase is over but, until recently, important and, to some extent, unexpected results were achieved. An updated review of selected experimental results is presented, as well as a survey of perspectives for future studies.

“…Secondary particle channels have been designed (see, for example [27,32,33]) at a number of different facilities that would serve the application described here as well. They employ one, usually two Wien filters [34] (crossed E and B field regions) to select either π or K beams.…”

Over the past two decades, meson photo-and electroproduction data of unprecedented quality and quantity have been measured at electromagnetic facilities worldwide. By contrast, the meson-beam data for the same hadronic final states are mostly outdated and largely of poor quality, or even nonexistent, and thus provide inadequate input to help interpret, analyze, and exploit the full potential of the new electromagnetic data. To reap the full benefit of the high-precision electromagnetic data, new high-statistics data from measurements with meson beams, with good angle and energy coverage for a wide range of reactions, are critically needed to advance our knowledge in baryon and meson spectroscopy and other related areas of hadron physics. To address this situation, a stateof-the-art meson-beam facility needs to be constructed. The present paper summarizes unresolved issues in hadron physics and outlines the vast opportunities and advances that only become possible with such a facility.

“…It means the sticking probability of the Ξ − would be small; the production cross section of the order of 10-100 nb/sr was estimated. Therefore, we need a high-intensity ( 10 6 K − /s) and good-purity (K − /π − 1) K − beam line such as BNL AGS D6 beam line [6] and K1.8 beam line at J-PARC [7]. The outgoing K + momentum is about 1.3 GeV/c, which is rather high momentum.…”

“…A New High-resolution Spectrometer for S=-2 Hypernuclear Study Shunsuke Kanatsuki There are two emulsion events which have a unique identification of a double-Λ hypernucleus, 6 ΛΛ He (Nagara event [1,2]) and a deep bound state of Ξ − -14 N system (Kiso event [3]). These two emulsion events suggest the Λ-Λ interaction is weakly attractive by 0.67±0.17 MeV and the existence of strongly bound Ξ hypernuclear state.…”

Spectroscopy of strangeness −2 systems has not been greatly in progress, because of the limited K − beam intensity to produce such systems and the limited energy resolution to identify them. Increasing K − beam intensity at J-PARC will enable us to carry out the spectroscopy by improving the energy resolution of the spectrometers in one order of magnitude from 14 MeV to 2 MeV. The status of the new spectrometer S − 2S is reported.
