Investigation of the Forward Structure in Charge-ExchangeK*0(890)Production

Abstract

We present an investigation of the reaction $K^{-}p\to K^{{*}^0}\mathrm{}\left(890\right)n$ at 3.9 and 4.6 $\frac{\mathrm{GeV}}{c}$ incident momenta. The order-of-magnitude increase in statistics with respect to previous analysis allows an investigation of the $K^{{*}^0}\mathrm{}\left(890\right)\mathrm{}$-production properties in the very forward region of momentum transfer and also provides a quantitative test of the absorption-modified one-pion exchange model. This model gives an excellent description of the differential cross sections and decay correlations at the two energies.
