The $R^2$ gauge theory
Comments: 15 pages, 2 figures, title changed

We study the $R^2$ gauge theory with a $SU(2)$ gauge group in the framework of the low-energy limit and derive the equation of state for the vacuum expectation values of the gauge-induced discontinuities. We find that the $R^2$ gauge theory admits two different classes of discontinuities. The first one is the differential-valued-expansion-symmetric one. The second one is the restricted-symmetric-expansion one. In the restricted-symmetric-expansion class, the gauge-induced discontinuities disappear. In this case, we infer the $R^2$ gauge theory in the low-energy limit.
