We study the total cross-section of high energy collisions in the one-instanton sector of purely bosonic theories with instantons. We find that in the limit g2 → 0, E/E sph = fixed , the leading behavior of the total cross-section is σ lot ~ exp [1/g2(−2S0 + F(E/E sph ))], where S0 is the instanton action. In the electroweak theory at E/E sph ≪ 1, the function F(E/E sph ) is determined by the gauge boson part of the instanton configuration and its explicit form is found.

We present the dynamical string model of high-energy hadronic processes, developed by us recently. To describe the dynamical aspects of the decay of hadrons and those of the hadron-hadron interaction correctly, a semiclassical unified string-flux tube model of hadrons is used. Specific aspects of this model are discussed: (i) the transverse extension of gluon flux tubes, (ii) the decay of highly excited flux tubes, (iii) the gluon structure functions of hadronic flux tubes and their connection with the total cross section of the flux tube-flux tube interaction at high energies. The dynamical string model is applied to the numerical simulation of e+e− annihilation and pp collision at high energies.

The 2S excitation cross section of atomic hydrogen by electron impact at high energies has been calculated following the method of Das. Comparison of the results for the differential cross section with other theoretical results, and comparison of the results for the total cross section with those of other theories and experiments, shows that the results of the present calculations are fairly accurate.

Nucleus-nucleus elastic scattering at ultra-high energy is studied within the scheme of Glauber multiple scattering and also within the geometrical picture of the Chou-Yang model. Both models offer a reasonable explanation of a recent CERN experiment on a-a elastic scattering and their differences are discussed. Results are presented for (X-a elastic scattering at ultra-high energies, and for a-9Be, a_1 2C, a_1 60 and a_24Mg elastic scatterings at currently accessible energies. The A dependence of the total cross section is approximately An with n ~ 0�55.
