Evidence for $η_{c} (2 S) \to p p ˉ π^{+} π^{-} π^{0}$ and observation of $χ_{c J} \to p p ˉ π^{+} π^{-} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Using $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII detector at the BEPCII collider, the $ψ (3686) \to γ p p ˉ π^{+} π^{-} π^{0}$ process is investigated. Evidence…

Measurement of Branching Fraction and Transition Magnetic Moment of the Hyperon Dalitz Decay $Σ^{0} \to Λ e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Based on a data sample of 10 billion $J / ψ$ events collected with the BESIII detector operating at the BEPCII collider, the Dalitz decay $Σ^{0} \to Λ e^{+} e^{-}$ is studied experim…

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…
