Full homomorphisms to graph classes

Pavol Hell, César Hernández-Cruz

Given a family of graphs $F$ , we define a graph $G$ to be fully $F$ -colourable if $G$ admits a full homomorphism to some $F$ in $F$ . We approach the p…

Measurement of the double Dalitz decay $I^\cdot \to e^{+} e^{-} e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

The BESIII experiment measured the rare decay of the eta meson into two electron-positron pairs, determining its branching fraction to be about 2.6 × 10⁻⁵.
