|Abstract:||The reliable values of effective strong coupling constants (as) for hadrons from various reactions have been found by investigating experimentally. So far, it has been proved that the as is not a fixed quantity. In this paper, we show that how the value of as depends on the constituent quark masses in hadrons. The effective values of as for different quark masses can be determined by using short-range attractive hyper-Coulombic potential, which would be in agreement with ln(q2/m2).|
