标题： Nonminimal GUT inflation after Planck results

摘要： 在本工作中，我们研究了与引力非最小耦合的GUT Coleman-Weinberg暴胀模型。 在这种模型中，通常发现非最小耦合很大或者标量场自耦合异常小。 我们在这里表明，该模型对于耦合的自然值与普朗克的最新结果一致。 显示英文摘要

摘要： In the present work we study GUT Coleman-Weinberg inflation with a nonminimal coupling to gravity. In this kind of model one usually finds that either the nonminimal coupling is large or the inflaton self-coupling in unnaturally small. We have shown here that the model is in agreement with the recent results from Planck for natural values of the couplings.
