Scaling behavior of spectra of protons, deuterons, and tritons produced with high transverse momenta in $pA$ and $^{12}CA$ collisions

The first data on the yield of the lightest nuclear fragments (protons $p$, deuterons $d$, and tritons $t$) with high transverse momenta $p_{\mathrm{T}}$ at an angle of $40^\circ$ in the laboratory reference frame from nuclear targets bombarded by $50$-GeV/$c$ protons and $20A$-GeV/$c$ carbon nuclei obtained in the SPIN experiment (IHEP, Protvino, Russia) have been reported. It has been shown that the $pA$ and $CA$ data can be described within a common scaling approach, which possibly indicates that the mechanism of formation of high-$p_{\mathrm{T}}$ nuclear fragments is common for these reactions.
