$K^{*0\mathrm{}}$ and ${K_S}^0$ Meson Production in $e^{+}{e}^{-}$ Annihilations at 29 GeV

The inclusive production cross sections and transverse momentum distributions of $K^{*0\mathrm{}}$ and ${K_S}^0$ mesons in $e^{+}{e}^{-}$ annihilation at a center-of-mass energy of 29 GeV have been measured by means of the time projection chamber detector in the PEP-4 experiment. The mean multiplicites are found to be 0.49 ± 0.04(stat.) ± 0.07(syst.) ($K^{*0\mathrm{}}+{\bar{K}}^{*0\mathrm{}}$) and 1.22 ± 0.03(stat.) ±0.15(syst.) ($K^0+{\bar{K}}^0$) per event.
