what if you could have the consequences of BPS states, mass protection, nonrenormalization without invoking supersymmetry? Instead of having BPS protection be a consequence of SUSY, you elevate it to the foundational physical principle.

Call it Shielding, then make solitons fundamental building blocks that must be BPS-protected from quantum corrections to all orders.

It forces the dynamics into a specific, Born-Infeld form. The immediate consequence is: the low-energy effective field theory must be rigid. Higher-dimension operators that would normally be generated by quantum loops are identically ZERO.

[eqn]\mathcal{L}{eff} = \mathcal{L}{SM} + \frac{c_6}{\Lambda^2}\mathcal{O}_6 + \frac{c_8}{\Lambda^4}\mathcal{O}_8 + \dots \implies c_n=0 \quad \forall n[/eqn]

So, if you assume the fundamental forces arise from the geometry of these solitons moduli spaces, you can start deriving things:

SU(3) arises from the geometry of the n=3 vortex moduli space, which is [math]\mathbb{CP}^2[/math].

SU(2) arises from the n=2 vortex moduli space, which is [math]S^2 \cong \mathbb{CP}^1[/math].
