Abstract

We study the production of K⁺, ρ, ω and ϕ mesons in p + ¹²C reactions on the basis of empirical spectral functions. The high momentum, high removal energy part of the spectral function is found to be negligible in all cases close to the absolute threshold. Furthermore, the two-step process (pN → πN N; πN → N + K⁺, ρ, ω, ϕ) dominates the cross section at threshold energies in line with earlier calculations based on the folding model.
