The strangeness S = −2 baryon-baryon interaction is investigated directly from the fundamental
theory of the strong interaction, QCD. The HAL QCD method enables us to extract baryon
interactions from the Nambu-Bethe-Salpeter wave functions without using any experimental information.
We discuss the properties of the S=−2 baryon-baryon potentials which are calculated
by using the (almost) physical point gauge configurations with large lattice volume of (8.1fm)4
generated on the K-computer.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
