Abstract

We consider Λ and Λ¯ production in a wide range of proton scattering experiments. The produced Λ and Λ¯ may or may not contain a diquark remnant of the beam proton. The ratio of these two production mechanisms is found to be a simple universal function r=[κ/(y_p−y)]ⁱ of the rapidity difference y_p−y of the beam proton and the produced Λ or Λ¯, valid over four orders of magnitude, from r≈0.01 to r≈100, with κ=2.86±0.03±0.07, and i=4.39±0.06±0.15.
