Abstract

In this work, we perform a combined analysis to the measured data of the cross section of open-strange processes e+eK+Ke^+e^- \to K^+K^-, e+eKKˉ+c.c.e^+e^- \to K\bar{K}^{*}+c.c., e+eK+Ke^+e^- \to K^{*+}K^{*-}, e+eK1(1270)+Ke^+e^- \to K_1(1270)^+K^-, e+eK1(1400)+Ke^+e^- \to K_1(1400)^+K^-, e+eK2(1430)Kˉ+c.c.e^+e^- \to K_2^{*}(1430)\bar{K}+c.c. and e+eK(1460)+Ke^+e^- \to K(1460)^+K^- with the support of study of hadron spectroscopy. We reveal the contribution of the possible light vector mesons around 2 GeV to reproduce the cross section data of the reported open-strange processes from e+ee^+e^- annihilation which may provide a new perspective to construct the light vector meson family and understand the Y(2175)Y(2175).
