Physicists in Italy have discovered the first evidence of a rare
nucleus that doesn’t exist in nature and lives for just 10-10 seconds before decaying. It’s a type of hypernucleus
that, like all nuclei, contains an assortment of neutrons and protons. But unlike ordinary nuclei, hypernuclei also contain
at least one hyperon, a particle that consists of three quarks, including at least one strange quark. Hypernuclei are thought
to form the core of strange matter that may exist in distant parts of the universe, and could also allow physicists to probe
the inside of the nucleus.
