Observation of the Antimatter Hypernucleus $_{I^ˉ }^{4} H$

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +350

At the origin of the Universe, asymmetry between the amount of created matter and antimatter led to the matter-dominated Universe as we know today. The origins of this asymmetry re…

First Observation of a Three-Resonance Structure in $e^{+} e^{-} \to$ Nonopen Charm Hadrons

BESIII Collaboration, M. Ablikim, M. N. Achasov +619

We report the measurement of the inclusive cross sections for $e^{+} e^{-}$ $\to$ nOCH (where nOCH denotes non-open charm hadrons) with improved precision at center-of-mass (c.m.)…
