Coupling Constant

My question isnt directly related to Root, but if any one could solve this it would be a great help,
does any one know how to calculate/ measure value of alpha_s (strong coupling constant)? is there any formula or any theory?

Thankyou!

Maybe @moneta can help

@moneta can you help?

I think the same question you already asked on stackexchange is perfectly answered there: there is no formula, it can only be found experimentally.
