Abstract
The amplitudes of hadron-hadron forward elastic scattering at high energies are investigated on the basis of analyticity and crossing symmetry. A universal uniformizing variable for them is proposed, and the formulas for crossing-even and crossing-odd amplitudes are derived. The same parameters in these formulas determine the real and imaginary (total cross sections) parts of the amplitudes. The analysis of the parameters determined from experimental data clearly points to the quark-gluon structure of hadron total cross sections. The total cross sections for hyperon-proton scattering are predicted. They are consistent with experimental data and, in particular, with the new SELEX-collaboration measurement σ tot(Σ− p).
