How to avoid the ordinary Coulomb solution in QCD?
First, I think your proposed current would break gauge invariance, but that's a relatively trivial problem in that I think you could reformulate your question getting around that issue.
The bigger ...

$ \pi^0\to \gamma\gamma$ parity conservation
As @Cosmas Zachos said in his comment, the Levi-Civita pseudotensor $\epsilon$ has negative parity. But why?
This is the case because $\epsilon_{\mu\nu\rho\sigma} := \sqrt{-g}\ \varepsilon_{\mu\nu\rho\...

How can dense quark matter stabilize wormholes?
These papers use the MIT Bag model, which treats the difference between the non-perturbative QCD vacuum from the perturbative vacuum inside of hadrons by a simple bag constant. For valance quarks that ...
