我们将螺旋暴胀的想法应用于科尔曼-温伯格势,并表明即使四次耦合 $\lambda$ 为 $\mathcal{O}(0.1)$,从中间尺度到 GUT 尺度的对称破缺尺度也允许暴胀与井观测相匹配。在 GUT 尺度对称性破缺的情况下,张量与标量的比率可以为 $\mathcal{O}(0.01)$。
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 $\lambda$ is of $\mathcal{O}(0.1)$. The tensor-to-scalar ratio can be of $\mathcal{O}(0.01)$ in case of GUT scale symmetry-breaking.
