ReggeizedU(6)×U(6)×O(3)and Absorptive Correction Cuts for½+−→ 0½+−Charge-Exchange Reactions

Abstract

Reggeized $U\left(6\right)\mathrm{}\times U\left(6\right)\mathrm{}\times O\left(3\right)\mathrm{}$ with absorptive corrections is applied to some 0${}_{}{}^{-}{}_{}{}^{}\mathrm{½}_{}^{+}{}_{}{}^{}$ → 0${}_{}{}^{-}{}_{}{}^{}\mathrm{½}_{}^{+}{}_{}{}^{}$ charge-exchange processes. The differential cross sections for ${\pi }^{-}p\to {\pi }^{0}n$ and ${\pi }^{-}p\to {\eta }^{0}n$ are used to fix the parameters of the $\rho$ and $A_2$ trajectories, respectively. With these parameters, an absolute prediction is made for the process $K^{-}p\to {\overline{K}}^{0}n$. The agreement with experiment is good. The polarization parameter $P\left(t\right)\mathrm{}$ and the Wolfenstein parameters $A\left(t\right)\mathrm{}$ and $R\left(t\right)\mathrm{}$ are also presented.
