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…

First measurements of the branching fractions of $J / ψ$ and $ψ (3686) \to Σ^{0} Σ ˉ^{0} η$

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

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ and $(2712 \pm 14) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the hadronic decays $J/ψ\to…

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…

Search for the charged lepton flavour violating decay $η^{'} \to e μ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Based on $(8998 \pm 40) \times 1 0^{6}$ $J / ψ$ events collected in $e^{+} e^{-}$ collisions at $s = 3.097$ GeV with the BESIII detector, we present a search for the charged lepton flavou…

Search for the $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decay

Belle, Belle II Collaborations, : +432

We present the first search for $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decays. We look for signal decays in $B^{0} B ˉ^{0}$ events produced in asymmetric-energy electron-positron collisions.…
