NICA fixed target mode: Soft jet studies in the relative 4-velocity space

“…Such behavior of T ( √ s) agrees well with the features of T k ( √ s) ( Fig. 1c, d) and confirms the hypothesis with regard to the changing of the dynamical regimes of multiparticle production at √ s ∼ 5 GeV [4]. [6,7].…”

“…One can see a qualitatively similar character of the energy dependence for all parameters from the set G at the respective values ofX. Figure 1 shows that, for any value of i, the dependencies G i ( √ s) exhibit a change in behavior in the region around √ s ≃ 3 GeV for all interaction types, with the exception of hA, at any value ofX, and this confirms the hypothesis put forth in [4] that dynamical interaction regimes undergo a change for √ s < 3 − 4 GeV. In the region of √ s < 4 GeV, experimental dependencies G i ( √ s), i = 1 − 3, for all interaction types, with the exception of hA, are approximated by the function in (1).…”

“…Taking into account the results for b k ( √ s) in the region of √ s > 3.5 GeV [4,5] and the behavior of T k ( √ s) and D( √ s) in the above range of √ s, we approximated by the function (2) the samples taken for T k and D and summed over the fragmentation regions. The numerical values of the fit parameters and the respective detailed discussion are presented in [6].…”

“…. Special features of this method in the case of the production of two jets were considered in detail in [3,4,5,6,7]. In that case, secondary particles refer to the region of target (beam) frag-…”

“…The quantity b k is the square of the distance of the k th particle from the jet axis V in the space of U k . The "temperature" defined as the mean kinetic energy of particles in the jet rest frame, T k , is estimated on the basis of the invariant functions F (b k ) that, for pion jets, have the form [4]…”
