I am trying to get an intuitive understanding of how fiber bundles can describe gauge theories. Gauge fields transform in the adjoint representation and can be decomposed as:

W

_{μ}= W

_{μ}

^{a}t

_{a}

Gauge field = Gauge group x generators in the adjoint representation.

I have been reading about principle G-bundles where the manifold and the fiber correspond to the gauge group, G. However, I can't quite relate this to the above. Can someone help me understand this is layman's terms.
