Unitarity, analyticity and the idea of duality combination allowed us to solve the problem of confinement, preventing the application of quantum chromodynamics to hadron scattering and resonance processes. This allowed us to construct explicit expressions for the cross sections of scattering and particle formation processes. The fundamental principles of the theory have been complemented by Monte Carlo numerical methods, PYTHIA and a computing package developed by CERN such as the ROOT package includes MINUIT, the efficient minimization program needed to theoretical prediction with the experimental data. The use of new experimentally measured cross sections of strange neutral hadrons generation (??0, Λ and Λ̅) at proton-lead collision energy √(sNN) = 8.16 is a necessary scientific material for developing and selecting reliable theoretical models that forecast patterns in the relativistic heavy nuclei collisions conditioned by effects of cold nuclear matter and/or the formation of quark-gluon plasma. Comissioning of the RMS-R3 for tracking the collision conditions of LHC beams and background at LHCb experiment is the original contribution of the project authors to the modernization of the LHCb experiment (LHCb Upgrade I). The original development of the solid-state micro-target LHCb-MEMS-target prototype is aimed at significantly expanding the range of nuclear systems collided at LHC, and collision energies in the region √sNN = 0.1 TeV, including searches for QGP signals in the poorly known QCD phase diagram area. We have proposed a method of ensuring a stable intensity of beam collisions with nuclei of a fixed solid-state target by correcting of the target position in the beam halo by a microstep motor. A formalism has been worked out to describe the decrease in beam intensity under the influence of various factors. We performed analytical calculations and modeling for proton beam.
