Electron spin magnetic moment by unphysical Dirac equation contradicts QED.

Dirac equation's unphysical γ matrix fake spin.

(Fig.1)  Dirac equation expresses electron spin (= σμν ) as unphysical γ matrices .

Relativistic quantum field theory = Dirac equation baselessly claims the (unphysical) γ matrices may indicate (illusory) spin.

Relativistic quantum field theory or QED relies on unphysical relativistic Dirac equation's γ matrices as (illusory) electron spin (= σμν = iγμγν,  this-p.6-p.16 ).

↑ This relativistic Dirac equation's artificial spin has nothing to do with the real world's phenomena.

Relativistic (illusory) spin is just unphysical γ matrix lacking reality.

(Fig.2)  ↓ unphysical artificial γ matrices = (illusory) spin ?

Using the unphysical γ matrices in relativistic Dirac equation, we get Fig.2 equation including the unphysical spin σμν 4 × 4 matrices.

This page uses (-1, +1, +1, +1) version of relativistic metric notation.

Artificial math trick of Dirac γ matrices to get the electron's spin magnetic moment.

By multiplying both sides of Fig.2 by pν u(p) and using Dirac equation, we get Fig.4 and Fig.4'.

About the notation, AνBν = A0B0 + A1B1 + A2B2 + A3B3 = -A0B0 + A1B1 + A2B2 + A3B3

In the same way as Fig.4, we can get Fig.5 and Fig.5'.

(Fig.6)

By multiplying Fig.4' and Fig.5' by Fig.6- u or bar-u operator of Dirac equation, and summing them, we get Fig.7.

Unphysical Dirac equation just manipulating γ matrices cannot predict electron's magnetic moment at all.

(Fig.7)  Artificial math trick of linking Dirac γ matrices to magnetic moment, which is Not prediction by (useless) relativistic Dirac equation.

Dirac equation cannot predict spin magnetic moment, instead, it just artificially manipulates it using unphysical γ matrices.

From Fig.4', Fig.5' and Fig.6, we obtain Fig.7 where the coefficient of the unphysical σμν is said to resemble the electron's magnetic moment (= Bohr magneton, this-p.2,  this-p.12 ), which ad-hoc artificial process is called Gordon decomposition identity ( this-p.4,  this-p.18,  this-p.3-lower,  this-p.12 ).

As shown here, the relativistic unphysical Dirac equation just artificially manipulating the unphysical γ matrices can Not predict the electron's magnetic moment or g-factor = 2, contrary to the standard explanation.

Dirac spin g-factor contradicts QED derivation of anomalous magnetic moment (= g-2 factor ).

(Fig.8) ↓ Different inconsistent rules are applied to get Dirac spin g-factor (= 2 ) and QED anomalous magnetic moment (= g-2 ), which is Not prediction.

QED using the different inconsistent rules is useless, unable to predict the spin (anomalous) magnetic moment.

As shown in Fig.7 and Fig.8-artificial change-1, Dirac equation tries to artificially change the unphysical γ matrix into ( p' + p ) term (= momentum ? ) and σμν allegedly representing electron spin magnetic moment (= g = 2 ?  this-p.8,p.10 ).

↑ This Dirac equation's derivation of electron spin g-factor or magnetic moment (= g= 2 ) is inconsistent with QED derivation of electron's smaller anomalous magnetic moment (= g-2 = 0.00116,  this-p.13-14,  this-p.3-p.4 ).

Because in QED calculation of electron anomalous magnetic moment, they use the different ad-hoc rule of artificially changing ( p' + p ) term into γ term (= illegitimately removed by renormalization ) and σμν (= this-artificial change-2 ), which is inconsistent with the above Dirac derivation of magnetic moment changing the γ matric into ( p' + p ) term and the spin σμν term (= this-artificial change-1 ).

Getting Dirac spin g=2 magnetic moment is inconsistent with QED's ad-hoc method of getting g - 2 anomalous magnetic moment.

In Dirac's g = 2 factor in artificial change-1 of Fig.8, if they try to change ( p' + p ) term into other terms like anomalous magnetic moment of g-2 in artificial change-2, the spin term σμν (= allegedly expressing the original spin g-factor of g = 2 ) also disappears (= so this cannot get the electron's spin magnetic moment g = 2 ), and only γμ term remains.  ← It means they get only Dirac g=2 factor or only the much smaller anomalous magnetic moment value of g - 2, if they try to apply the common change rule.

↑ Applying the inconsistent ad-hoc rules to Dirac's magnetic moment (= g = 2 ) and QED anomalous magnetic moment (= g - 2,  this-p.3-(14)(17) ) means QED and relativistic Dirac equation are illegitimate, lacking power to predict any physical values such as anomalous magnetic moment.
