How to understand the underlying structures of X(4140), X(4274), X(4500) and X(4700)
We investigate the possible rescattering effects which may contribute to the process B+→J/ψϕK+. It is shown that the ψ′ϕ rescattering via the ψ′K1 loop can simulate the structure of X(4700). The cusp effect due to the Ds⁎+Ds− rescattering may possibly simulate the X(4140) structure, but it depends o...
