New Electroweak precision measurements

CMS of LHC (CERN) has just reported new Electroweak precision measurements {(sin(θ), lepton/eff)^2 = 0.23101±0.00052} on November 14, 2017, see https://arxiv.org/abs/1711.05288 .

In Standard Model, Weinberg angle is a function of two more fundamental physical constants: weak isospin g and weak hypercharge g’, and they are all ‘free parameters’ (not derived theoretically).

On the other hand, the Weinberg angle was calculated theoretically in G-theory, see http://prebabel.blogspot.com/2011/10/theoretical-calculation-of-cabibbo-and.html or page 36 of ‘Super Unified Theory”.

In fact, the Weinberg angle (θ) is precisely defined by the equation (10), page 37 of ‘Super Unified Theory”, as follows.

     Sin (Δ θ1) =  Sin^2 (Δ θ2) = (Sin^2   Δ θ3) ^2 = (Sin^3 Δ θ4) ^3

= (Sin^6 Δ θ5) ^6 = (Sin^64 Δ θ6) ^64 ……. Equation (10)

 

  Sin (Δ θ1) = Sin {A (1) – 3 (A (0)/24}

= Sin {Cabibbo angle (θc)) – 3 (A (0)/24} = 0.23067

 

Sin^2 (Δ θ2 = 28.75°; Weinberg angle (θW)) = 0.2313502

Δ θ2 = 28.75° (Weinberg angle (θ))

 

{Sin (Δ θ1) + Sin^2 (Δ θ2)}/2 = 0.2310

All Δ θn are mixing angles.
