The value derived for g0 is simply 2/pi.
We assume that the observable coupling
constants e, g and g' contain both a charge
interaction term as well as a spin term:
e = ( 1 + spin_term) e0
g = ( 1 + spin_term) g0
charge_term = 1
spin_term = alpha( 1 + alpha/(2pi) )
Where 1+alpha/(2pi) is the magnetic moment.
This gives us the "charge-interaction-only"
coupling constants:
e0 = spin-less electromagnetic coupling e
g0 = spin-less electroweak coupling g
Which turn out to be both simple
mathematical values. With alpha=e^2/4pi)
we get:
1/ 139. 045 636 8 (1) = alpha0
1/ 139. 045 636 6 = exp(-pi^2/2)
0. 636 52 (47) = g0
0. 636 62 = 2/pi
