Abstract
We apply the idea of spiral inflation to Coleman-Weinberg potential, and show that inflation matching well observations is allowed for a symmetry-breaking scale ranging from an intermediate scale to GUT scale even if the quartic coupling is of . The tensor-to-scalar ratio can be of in case of GUT scale symmetry-breaking.
