🔬 For 25 years, physicists had fully identified just ONE nucleus holding two Lambda particles.
Now RIKEN has a second. AI scanned microscope images of film with ~1M particle tracks per cm². AI narrowed it down; humans made the call.

Observation of the antimatter hypernucleus $${}_{\bar{{\boldsymbol{\Lambda }}}}{}^{{\bf{4}}}\bar{{\bf{H}}}$$ H ¯ Λ ¯ 4 - Nature
An antimatter hypernucleus formed by an anti-lambda hadron, an antiproton and two antineutrons was observed through its two-body decay after production in ultrarelativistic heavy-ion collisions.

AI uncovers double-strangeness: A new double-Lambda hypernucleus
Researchers from the High Energy Nuclear Physics Laboratory at the RIKEN Pioneering Research Institute (PRI) in Japan and their international collaborators have made a discovery that bridges artificial intelligence and nuclear physics. By applying deep learning techniques to a vast amount of unexamined nuclear emulsion data from the J-PARC E07 experiment, the team identified, for the first time in 25 years, a new double-Lambda hypernucleus.
