A remark concerning the backward-forward asymmetry in Λ0-decay

High-Energy Nucleon-Nucleon Collisions

“…3 The situation has been reviewed by Salmeron and Zichichi. 4 They have applied criteria which supposedly eliminate all biases and give an over-all result for (cdPf or e-aft)av of -0.56=fc0.15, a 3-standard-deviation effect. No such asymmetries in the plane of production have been found at Berkeley in w~+p -> A+i£° hydrogen events.…”
