The 𝑝_𝑇 spectrums of (a) 𝜋⁺, 𝐾⁺,   and 𝑝; (b) 𝜋⁻, 𝐾⁻, and 𝑝; and (c) 𝐾⁰_𝑠, Λ, Λ,   𝜙, and Ξ⁻+Ξ⁺ produced in p-p collisions at 0.9 TeV. The symbols represent experimental data of the ALICE Collaboration [19, 20]. The solid and dashed curves represent results calculated by using the multicomponent Erlang distribution and the Lévy distribution, respectively.
