Abstract: (APS)
We suggest that the invariant cross section for a+b→c+X should be plotted in terms of (x̃,P⊥), where x̃=2E*s and E* is the energy of particle c in the center-of-mass system. We have shown for processes with exotic abc¯ [such as p+p→(π±,K±,p¯)+X] that the invariant cross sections Ed3σd3p→f(x̃,P⊥) at P⊥=0.2, 0.4, and 0.8 GeV/c over an energy range of Pinc=12−1500 GeV/c. Furthermore, scaling in terms of (x̃,P⊥) provides a natural connection between the small-P⊥ and large-P⊥ regions. Predictions on the single-particle distribution when both P∥* and P⊥* are large are also presented.
