We offer to your attention a preprint “Two different distance scales of q² and V_QCD potential of protons from π⁻C interactions at 40 GeV/c” E1-2022-20 published by the JINR Publishing Department. The authors are Baatar Ts. et al.

Authors of this scientific paper have expressed the formula for the four-momentum squared q² as a function of two different distance scales r₁ and r₂. This procedure necessitates taking into account an additional derivative from the formula for q² (or the running coupling constant of α_s(q²)). The force using the potential VQCD(r₂) has been calculated. The impact of r₂ parameter on the force has also been studied.

The investigation has been performed jointly with the Institute of Physics and Technology of the Mongolian Academy of Sciences at the Veksler and Baldin Laboratory of High Energy Physics JINR. The article has been submitted to the Physics of Atomic Nuclei journal.
