Lagrangian strong form

Thus the Lagrangian strong form [LSF] which is equivalent to the weak form (4.38) is given by... 

Each Kn in Eq. (8) has a different overall phase, which arises because a different Lagrangian can be used for each value of n. However, there is a strong constraint on these phases, which arises because the set of Kernels must form... 

In the PCL the strong interaction Lagrangian of vector mesons with vector and pseudoscalar mesons has the form... 

The next diagram (FIG. 3) also does not contribute to the partial width for the 0 — W7r° decay. In this case the Lagrangian of the strong coupling of axial-vector mesons to vector and pseudoscalar mesons is derived in a similar way and has the form (Nasriddinov, 1994)... 

This result is a curious and troubling one for the prospect that there can be a classical B held that has real dynamics. This would imply that non-Abelian symmetry is determined by a Lagrangian of the form ( 32 — /i, 2J, where this is automatically zero by duality. However, if this were the case, we would still have non-Abelian symmetry as a nonLagrangian symmetry. This strongly supports the possibility that the electrodynamic vacuum will continue to exhibit non-Abelian symmetries, such as squeezed states, even if we impose E3 = B3 = 0.
