dc.descriptionBased on duality, we previously proposed to use rich informations on pi p total cross sections below N=10GeV in addition to high-energy data in order to discriminate whether these cross sections increase like log nu or log2 nu at high energies. We then arrived at the conclusion that our analysis prefers the log2 nu behaviours. Using the FESR as a constraint for high energy parameters also for the pp, pbar p scattering, we search for the simultaneous best fit to the data points of sigma(tot) and rho ratio up to some energy (e.g., ISR, Tevatron) to determine the high-energy parameters. We then predict sigma(tot) and rho in the LHC and high-energy cosmic-ray regions. Using the data up to E=1.8TeV (Tevatron), we predict sigma(tot)pp and rho(pp) at the LHC energy (E=14TeV) as 106.3+- 5.1syst +- 2.4stat mb and 0.126 +- 0.007syst +- 0.004stat, respectively. The predicted values of sigma(tot) in terms of the same parameters are in good agreement with the cosmic-ray experimental data up to Plab = 10 (8--9) GeV.
