Froissaron-Maximal Odderon model was generalized for nonzero transfer momenta. The presence of odderon effects in the differential cross-section behavior at LHC energies was corroborated. The specific anisotropy in the angular lepton distribution with respect to the three-momentum pair in the synchrotron radiation model was calculated. The convincing reasons for this result as possible signal of synchrotron radiation occurrence in the respective experiments have been given. It was shown that a presence of such effect gives a possibility to solve contradictions between results of experiments and phenomenological models of direct photon production. The photon spectrum with large transverse momentum was calculated and compared with existing experimental data. It was shown that characteristics proper to this mechanism of lepton pair production distinguish it from other models of lepton pair production and can potentially provide the effective measurements of quark-gluon plasma production in experiments. The dependence of particle density in pseudorapidity on the event centrality and on the number of constituent nucleons for Xe-Xe interaction at energy 5.44 TeV and for p-Pb collisions at energy 8.16 TeV as well has been measured. Both HRG and UrQMD models have been used to calculate the kaon-to-pion ratio and negatively charged hadron number fluctuations in pp and A-A collisions at SPS LHC. The suggestions were formulated for new experiments at the LHC accelerators.
