论文摘要
我们研究了高斯 - 骨网 - dilaton重力中的欧几里得虫洞，以解释宇宙的创造。我们考虑了两种类型的DILATON耦合（即，弦乐启发的模型和高斯模型），我们获得了定性相似的结果。可能存在欧几里得虫洞，可以解释我们宇宙的可能起源，在Dilaton场位于Dilaton潜力的障碍物上。即使DILATON电位不满足慢速条件，该解决方案也可以存在。此外，概率高于具有相同最终条件的霍金 - 莫斯instanton的概率。因此，高斯 - 骨网 - 迪拉蒂顿重力中的欧几里得虫洞是一种可能的和可能的情况，它解释了我们宇宙的起源。
We investigate Euclidean wormholes in Gauss-Bonnet-dilaton gravity to explain the creation of the universe from nothing. We considered two types of dilaton couplings (i.e., the string-inspired model and the Gaussian model) and we obtained qualitatively similar results. There can exist Euclidean wormholes that explain the possible origin of our universe, where the dilaton field is located over the barrier of dilaton potential. This solution can exist even if dilaton potential does not satisfy slow-roll conditions. In addition, the probability is higher than that of the Hawking-Moss instanton with the same final condition. Therefore, Euclidean wormholes in Gauss-Bonnet-dilaton gravity are a possible and probable scenario, which explains the origin of our universe.
