论文摘要
我们通过应用变形的指数势来重新访问非规范性标量场。我们表明，与观察值相当一致，最终的情况可能导致通货膨胀可观察到可观察到的可观察结果，尤其是标量光谱指数和张量表与量表比。此外，该方案的一个重要优点是，所需的参数值，例如非规范性指数和规模以及潜在的指数和规模，不需要获得不自然的值，因此可以接受理论上的理由。因此，我们在替代方案方面获得了重大改进，并且在模型参数之间提出了更适合数据的模型参数之间的明显相关性，可以在将来的探针中测试。观察效率和理论依据的这种结合使手头的情况成为了通货膨胀描述的好候选者。
We revisit inflation with non-canonical scalar fields by applying deformed-steepness exponential potentials. We show that the resulting scenario can lead to inflationary observables, and in particular to scalar spectral index and tensor-to-scalar ratio, in remarkable agreement with observations. Additionally, a significant advantage of the scenario is that the required parameter values, such as the non-canonicality exponent and scale, as well as the potential exponent and scale, do not need to acquire unnatural values and hence can accept a theoretical justification. Hence, we obtain a significant improvement with respect to alternative schemes, and we present distinct correlations between the model parameters that better fit the data, which can be tested in future probes. This combination of observational efficiency and theoretical justification makes the scenario at hand a good candidate for the description of inflation.
