Quantitative Regge Expressions with Scaling for Experimentally Measured Fastπ±,K+Inclusive Spectra and Relation to Backward-Elastic-Scattering Data

We represent the spectra for fast ${\pi }^{+}$, ${\pi }^{-}$, $K^{+}$ secondaries in $\mathrm{pp}$ collisions in Reggeized forms that describe the experimental data measured at several energies and that scale at high energies. We relate the inclusive amplitudes obtained to backward elastic ${\pi }^{\pm }p$, $K^{+}p$ scattering and predict both their relative magnitudes and their energy and angle dependence.
