Heavy quarkonia and new hadrons with two heavy quarks

Yuping Guo, Chang-Zheng Yuan

We give a pedagogical introduction to heavy quarkonia -- bound states of a heavy quark and its antiquark (e.g., charmonium $c c ˉ$ , bottomonium $b b ˉ$ ) -- as well as to the…

Search for the weak decay $η^{'} \to K^{\pm} π^{\mp}$ and precise measurement of the branching fraction $B (J / ψ \to ϕ η^{'})$

BESIII Collaboration, M. Ablikim, M. N. Achasov +414

We present the first search for the rare decay of $η^{'}$ into $K^{\pm} π^{\mp}$ in $J / ψ \to ϕ η^{'}$ , using a sample of $1.3 \times 1 0^{9}$ $J / ψ$ events collected with the BESII…
