Charged particle multiplicity distributions
Multiplicity distribution of negative particles
Momentum distribution of grey track particles (low energetic protons), which are defined as positive particle in the velocity interval 0.2 < < 0.7.
Multiplicity distributions of grey track particles.
Multiplicity distribution (a), dispersion D (b) and D/n (c) for grey track particles in interactions on Al and Au, normalized to the corresponding interactions on Hydrogen.
Average number of negative particles in the left region ( -2.5 < y < -0.5 ) (a), average number of negative particles in the right region ( -0.5 < y < 1.5 ) (b) and the dispersion D2LR = (1/2)(D2 - D2nR - D2nL), as function of the number of grey track particles.
Multiplicity distributions of charged particles in the forward (y > 0) and backward (y < 0) hemisphere.
