The experimental data are compared to a data- based model for individual exclusive Lambda production channels in the same reaction. The contributions of intermediate resonances such as Sigma(1385), Delta(++), or N-* are considered in detail. In particular, the result of a partial- wave analysis accounts for the abundant pK(+) Lambda final state. Model and data show a reasonable agreement at midrapidities, while a difference is found for larger rapidities. A total Lambda production cross section in p + p collisions at root s = 3.18 GeV of sigma (p + p -> Lambda + X) = 207.3 +/- 1.3 (+6.0) (-7.3)(stat.) +/- 8.4(syst.) (+ 0.4) (- 0.5)(model.) mu b is found. Workplace Nuclear Physics Institute Contact Markéta Sommerová, sommerova@ujf.cas.cz, Tel.: 266 173 228 Year of Publishing 2018
