Abstract

Single particle distribution are investigated in the multiperipheral model. Our result says that in the small x region (|x| ≤0.2), the distribution functions depend on m_a^2x^2θ(x)(m_b^2x^2θ(-x)) and m_c^2+k_⊥^2, where a(b) is the projectile (target) and c is the detected secondary. The x- and k_⊥^2-dependences of the distribution functions are more sensitive for smaller m_c^2 and larger m_a^2(m_b^2). There features are supported by experimental data, and our model fits the data on both the transversal and longitudinal momentum distributions in the following collisions quite well: π^++p→π^-+ “X”, K+p→π+ “X”, p+p→π+ “X”, γ+p→π+ “X”, p+p→K+ “X”, K^++p→K̅^0+ “X” and γ+p→K+ “X”. The K/π ratio becomes 0.11, which is also in good agreement with the present experimental results.
