Abstract:
We propose the initial single chiral particle emission mechanism, with which the hidden-charm dikaon decays of higher charmonia and charmoniumlike states are studied. Calculating the distributions of differential decay width, we obtain the line shape of the J/ψK(+) invariant mass spectrum of ψ(i)→J/ψK(+)K(-), where ψ(i)=ψ(4415), Y(4660), and ψ(4790). Our numerical results show that there exist enhancement structures with both hidden-charm and open-strange channels, which are near the D̄(s)(*)/D(*)D̄(s) and D(*)D̄(s)(*)/D̄(*)D(s)(*) thresholds. These charged charmoniumlike structures predicted in this Letter can be accessible in future experiments, especially BESIII, BelleII, and SuperB.

Electron Behavior
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
