Antipodal duality from the TGD point of view: answer to a question by Avi Shrikumar

Avi Shrikumar asked about the antipodal duality (see this), which has been discovered in QCD but whose origin is not well-understood.

Antipodal duality implies connections between strong and electroweak interactions, which look mysterious since in the standard model these interactions are apparently independent. This kind of connections were discovered long before QCD and expressed in terms of the conserved vector current hypothesis (CVC) and partially conserved axial current PCAC hypothesis for the current algebra.

I looked at the antipodal duality as I learned of it but did not find any obvious explanation in TGD at that time. After that I however managed to develop a rather detailed understanding of how the scattering amplitudes emerge in the TGD framework. The basic ideas about the construction of vertices (see this and this) are very helpful in the sequel.

1. In TGD, classical gravitational fields, color fields, electroweak fields are very closely related, being expressed in terms of CP₂ coordinates and their gradients, which define the basic field like variables when space-time surface 4-D M⁴ projection. TGD predicts that also M⁴ possesses Kähler structure and gives rise to the electroweak U(1) gauge field. It might give an additional contribution to the electroweak U(1) field or define an independent U(1) field.

There is also a Higgs emission vertex and the CP₂ part for the trace of the second fundamental fundamental form behaves like the Higgs group theoretically. This trace can be regarded as a generalized acceleration and satisfies the analog of Newton’ s equation and Einstein’s equations. M⁴ part as generalized M⁴ acceeration would naturally define graviton emission vertex and CP₂ part Higgs emission vertex.

This picture is bound to imply very strong connections between strong and weak interactions and also gravitation.

If this view is correct, then the standard model would reflect the underlying much deeper connection between electroweak, color and gravitational interactions implied by the geometrization of the standard model fields and gravitational fields.
