Deciphering the light vector meson contribution to the cross sections of $e^{+}{e}^{-}$ annihilations into the open-strange channels through a combined analysis

Abstract

In this work, we perform a combined analysis to the measured data of the cross section of open-strange processes $e^{+}{e}^{-}\to K^{+}{K}^{-}$, $e^{+}{e}^{-}\to K{\bar{K}}^{\ast }+c.c.$, $e^{+}{e}^{-}\to K^{\ast +}{K}^{\ast -}$, $e^{+}{e}^{-}\to K_1(1270{)}^{+}{K}^{-}$, $e^{+}{e}^{-}\to K_1(1400{)}^{+}{K}^{-}$, $e^{+}{e}^{-}\to K_2^{\ast }(1430)\bar{K}+c.c.$ and $e^{+}{e}^{-}\to K(1460{)}^{+}{K}^{-}$ 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 $e^{+}{e}^{-}$ annihilation which may provide a new perspective to construct the light vector meson family and understand the $Y(2175)$.
