Is the spin connection confined or condensed?

Understand

The spin connection enters the theory of gravity as a nonabelian gauge field associated with local Lorentz transformations.

• Normally it is eliminated from making an extra assumption - that of the metricity of the vierbein field.
• However, treated by itself with the usual gauge action, it has a negative beta function, implying that it is asymptotically free.
• I suggest that the spin connection could be confined (or perhaps partially confined) in the same way as other nonabelian gauge fields.
