A series of theoretical models have given excellent description to the observed energy dependence of the total cross section for the strangeness production process pp→pK~+ΛA and pp→pK~+∑~0. Compared to the delicate experimental and theoretical investigation in these two channels,there is only limited data on A series of theoretical models have given excellent description to the observed energy dependence of the total cross section for the strangeness production process pp → pK ~ + ΛA and pp → pK ~ + Σ ~ 0. two channels, there is only limited data on
