Measurement of the \boldsymbol{e^{+}e^{-}\to K^+K^-ψ(2S)} Cross Section at Center-of-Mass Energies from 4.699 to 4.951 GeV and Search for \boldsymbol{Z_{cs}^{\pm}} in the \boldsymbol{Z_{cs}^\pm\to K^\pmψ(2S)} 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. The measurements are carried out using several partial reconstruction techniques using data samples collected by the BESIII detector with a total integrated luminosity of... Show more
