Study of the Running Coupling Constant *a&sub(s)(q*2) of *p*– Mesons and Protons from p+p and p+C Interactions at 4.2 GeV/c / M.Urangua, A.I.Malakhov, B.Otgongerel, [a.o.] // Физика элементарных частиц и атомного ядра. – 2026. – Т. 57, № 5. – P. 1155. – URL: https://www1.jinr.ru/Pepan/v-57-5/69_Urangua_ann.pdf.

We focus on the study of the running coupling constant *a&sub(s)(q&sup(2) ) of *p&sup(−) mesons and protons from p + p and p +C interactions at 4.2 GeV/c. It is a well-known fact that the more correct value of the cut parameter *L&sub(QCD) in the formula of αs(q2 ) plays a very important role in obtaining the right values of this strong coupling constant *a&sub(s)(q&sup(2) ). In calculations, the previously obtained value of *L&sub(QCD) was used: *L&sub(QCD) =(ch^-) GeV = 0.197 GeV. The values of *a&sub(s)(q&sup(2) ) obtained with this cut parameter are compared to the QCD predictions.
