Coupling constants are unitized or unitless. Forces are associated to unitized coupling constants like charge (e), gravity (G), etc. All unitless coupling constants that I know of, like the fine structure constant ([tex]\alpha[/tex]), or the Lorentzian [tex]\beta[/tex], etc are ratios where the units cancel out.(adsbygoogle = window.adsbygoogle || []).push({});

As the weak coupling constant is unitless;

Does this mean it is a ratio of forces like the fine structure constant? If not why not.
