Structure of the Inclusive Pion Spectrum Nearx=0

Using a simplified multiperipheral model, we study the behavior of the longitudinal pion spectrum for the process $\mathrm{pp}\to \pi +$ anything in the region of small values of $x=\frac{2{p_{\parallel }}^{\mathrm{c}.\mathrm{m}.\mathrm{}}}{s^{\frac{1}{2}}}$. We expect the occurrence of an inverted cusp in the spectrum at very large energies and the appearance of noticeable effects at the energies of the CERN intersecting storage rings.
