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 $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ 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.…

Observation of $I^\cdot_{c} \to p p ˉ I^\cdot$ via $I ¨ (3686) \to I^^{3} p p ˉ I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

The study reports the first observation of the decay η_c → p p̄ η using a large ψ(3686) data set collected with the BESIII detector, and determines its branching fraction while acc…

Search for axion-like particles decaying to two photons at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +450

Axion-like particles (ALPs) are predicted in many extensions of the Standard Model and provide a well-motivated portal between visible and hidden sectors through their coupling to…
