Description
We investigate the running coupling constant $\alpha_s$($q^2$) for $\pi^-$-mesons and protons produced in $p+p$ and $p+C$ interaction at 10 GeV/c. The precise determination of $\alpha_s$($q^2$) critically depends on the choice of the cut-off parameter $\Lambda_{QCD}$ in its defining expression. For this analysis, we adopt $\Lambda_{QCD} = (c \hbar) GeV = 0.197 GeV$. The resulting $\alpha_s$($q^2$) values are computed and systematically compared with the theoretical predictions of Quantum Chromodynamics (QCD).
