The strong coupling constant: Its theoretical derivation from a geometric approach to hadron structure

Technical Report:

Abstract

Since more than a decade, a `bi-scale`, unified approach to strong and gravitational interactions has been proposed, that uses the geometrical methods of general relativity, and yielded results similar to `strong gravity` theory`s. The authors fix their attention, in this note, on hadron structure, and show that also the strong interaction strength {alpha}{sub S}, ordinarly called the `(pertubative) coupling-constant square`, can be evaluated within their theory, and found to decrease (increase) as the distances `r` decreases (increases). This yields both the confinement of the hadron constituents (for large values of r), and their asymptotic freedom (for small values of r inside the hadron): in qualitative agreement with the experimental evidence. Their approach lead, on a purely theoretical ground, to a dependence of {delta}{sub S} on r which had been previously found only on phenomenological and heuristical grounds. The authors expect the above agreement to be also quantitative, on the basis of a few checks performed in this paper, and of further works about calculating meson mass-spectra.
