Measurement of the ${\mathbf{e}}^{+}{\mathbf{e}}^{-}\to {\mathbf{K}}^{+}{\mathbf{K}}^{-}\mathbf{\psi }(2\mathbf{S})$ Cross Section at Center-of-Mass Energies from 4.699 to 4.951 GeV and Search for ${\mathbf{Z}}_{\mathbf{cs}}^{\pm }$ in the ${\mathbf{Z}}_{\mathbf{cs}}^{\pm }\to {\mathbf{K}}^{\pm }\mathbf{\psi }(2\mathbf{S})$ Decay

We perform the first investigation of the process $e^{+}{e}^{-}\to K^{+}{K}^{-}\psi (2S)$ and report its Born cross sections over a range of center-of-mass energies from 4.699 to 4.951~GeV. Th…
