摘　　要：Based on the Froissart-Martin theorem,the Regge theory and the possible Odderon exchange,the total cross-sectionσtot and the ratio of the real to imaginary parts of the forward scattering amplitude p in the pp and pp elastic collisions in the TOTEM energy region are studied in the FPO model.We consider the contributions of the Froissart bound and of the Pomeron,Reggeon and Odderon exchange terms in the scattering amplitude of the pp and pp elastic collisions.Using the Odderon interceptαo(0)=0.5,our theoretical predictions are in good agreement with the recent results of the TOTEM experiment.These results show that the Odderon,corresponding to the odd elastic scattering amplitude,is likely to exist.Based on the Froissart-Martin theorem,the Regge theory and the possible Odderon exchange,the total cross-section σtot and the ratio of the real to imaginary parts of the forward scattering amplitude p in the pp and pp elastic collisions in the TOTEM energy region are studied in the FPO model.We consider the contributions of the Froissart bound and of the Pomeron,Reggeon and Odderon exchange terms in the scattering amplitude of the pp and pp elastic collisions.Using the Odderon intercept αo（0）=0.5,our theoretical predictions are in good agreement with the recent results of the TOTEM experiment.These results show that the Odderon,corresponding to the odd elastic scattering amplitude,is likely to exist.
