Calculations of αS(q2) of π– Mesons and Protons from p +p and p + C Interactions at 10 GeV/c

In this paper we have calculated the values of the running coupling constants $${{\\alpha }_{S}}({{q}^{2}})$$ of $${{\\pi }^{ - }}$$ mesons and protons from $$p + p$$ and $$p + C$$ interactions at $$10\\,\\,{\\text{GeV/}}c$$ . The value of the cut parameter $${{\\Lambda }_{{{\\text{QCD}}}}}$$ obtained previously by the authors [1], was used: $${{\\Lambda }_{{{\\text{QCD}}}}} = (c\\hbar )\\,{\\text{GeV}} = 0.197\\,{\\text{GeV}}.$$ The results have been compared with QCD predictions.
