Abstract
In this work, firstly, we have determined the multiplicities of protons that are involved from projectiles to interactions, and secondly, the mean incident momentum using experimental data on the collisions of proton, helium, oxygen, silicon, and sulfur with the nuclear emulsion at 4.5A GeV/c. We have studied the dependences of clot numbers, number of particles in the clot, rapidity, and the mean azimuthal value on the variable dij, and the dependence of the cluster number on the mean value of the variable dij. Using the “Cone” algorithm for the clustering, we have precisely identified that the cut-off parameter to compose the clusters consisted of s and f tracks produced in (p, He, C, O, Si, S) + Em collisions decreases by the power law with mean values of incident momentum.

In this work, firstly, we have determined the multiplicities of protons that are involved from projectiles to interactions, and secondly, the mean incident momentum using experimental data on the collisions of proton, helium, oxygen, silicon, and sulfur with the nuclear emulsion at 4.5A GeV/c
For the (p, He, C, O, Si, S) + Em interactions detected by the nuclear emulsion track detector, the specific cut-off parameter in the chosen space should be determined for distinguishing the clusters reconstructed with the s and the f particles
We have chosen the two invariant quantities – the azimuthal angle (φ) and the pseudorapidity (η) of secondary particles produced by the interactions as mentioned above and have used the cone algorithm for distinguishing the clusters [10]
Summary
We have determined the multiplicities of protons that are involved from projectiles to interactions, and secondly, the mean incident momentum using experimental data on the collisions of proton, helium, oxygen, silicon, and sulfur with the nuclear emulsion at 4.5A GeV/c. Using the “Cone” algorithm for the clustering, we have precisely identified that the cut-off parameter to compose the clusters consisted of s and f tracks produced in (p, He, C, O, Si, S) + Em collisions decreases by the power law with mean values of incident momentum. With the photoemulsion experimental data, the dependence of the incident momentum of the cut-off parameter upon the type of colliding objects needs to be further studied.

The cut-off parameters for the clusters in these collisions are very important for studying resonance production
