We present a measurement of the production of $\Xi^-$ and $\Lambda\Lambda$ in the $^{12}$C$(K^-, K^+)$ reaction at an incident beam momentum of 1.8 GeV/$\mathit{c}$, based on high-statistics data from J-PARC E42. The cross section for the…

Both the FINUDA and AMADEUS experiments evidenced a low $\Sigma^+$ momentum component when investigating $\Sigma^+ \pi^-$ pairs produced in K$^-$ nuclear capture. This component is interpreted as a consequence of Gamov state formation, with…

The results of K-band-imaging observations of a candidate of an absorbed QSO at z=0.653, AX J131831+3341, are presented. The B-K color of the object is 4.85 mag, which is much redder than optically-selected QSOs. The K-band image shows…
