Using the experimental data from the STAR, PHENIX, ALICE, and CMS programs on the rapidity and energy dependence of the ${p}_{T}$ spectra in $p+p$ collisions, we show that a universal distribution exists. The energy dependence of temperature $T$ and parameter $n$ of the Tsallis distribution are also discussed in detail. A cascade particle production mechanism in $p+p$ collisions is proposed.
