It is argued that the cross sections of ultraperipheral interactions of heavy nuclei can become comparable in value to those of their ordinary hadronic interactions at high energies. Simple estimates of corresponding “preasymptotic energy thresholds” are provided. The method of equivalent photons is compared with the perturbative approach. The situation at NICA/FAIR energies is discussed.

The Magnetic Field

The magnetic field created in proton–proton and nucleus–nucleus collisions at ultra-high energies are studied with models of point-like charges and hard sphere for distribution of the constituents for vacuum conditions. The various beam ions are considered from light to heavy nuclei at energies corresponding to the nominal energies of the proton beam within the projects of further accelerator facilities high-energy Large Hadron Collider (HE-LHC) and Future Circular Collider (FCC). The magnetic-field strength immediately after collisions reaches the value tens of GeV 2 , while in the approach with point-like charges, some overestimate the amplitude of the field in comparison with more realistic hard-sphere model. The absolute value of the magnetic field rapidly decreases with time and increases with growth of atomic number. The amplitude for e B is estimated at level 100 GeV 2 to provide magnitude for quark–quark collisions at energies corresponding to the nominal energies of proton beams. These estimations are close to the range for onset of W boson condensation.

Good Agreement

Peripheral nucleon–nucleus collisions occur at high energies mainly through the interaction with one constituent quark from the incident nucleon. The central collisions should involve all three constituent quarks and each of them can interact several times. We calculate the average number of quark–nucleus interactions for both the cases in good agreement with the experimental data on [Formula: see text]-meson, [Formula: see text] and all charged secondaries productions in [Formula: see text] collisions at LHC energy [Formula: see text] TeV.

Squeeze Out

Microscopic VUU and QMD calculations, which include the momentum dependence of the nuclear interactions, both predict the observed collective off-plane squeeze-out of nuclear matter in heavy ion collisions. A strong projectile mass dependence is found, in agreement with the data. A fragment mass dependence of the emission pattern is predicted. The off-plane squeeze-out is sensitive to the bulk properties of hot and dense nuclear matter, namely the nuclear viscosity and the equation of state.
