Feynman x-spectra of $\overline{p}’\mathrm{s}$ for fixed c.m.s. angle tan θ = 2.66/$\sqrt{s}$ in pp-collisions at $\sqrt{s}$ = 31 (×10⁻²), 45 (×10⁻¹), and 53 GeV: parameterizations by Tan & Ng (1983) and Duperray et al. (2003) compared with experimental data (Albrow et al. 1973); the lines are labeled as in Figure 12.
