摘要:

结果表明,赛道通货膨胀可以实现在一个模稳定的情况下,一个超对称的上升D-长期。由此产生的模型是完全由一个有效的超引力理论描述,与原来的赛道模型。我们研究了暴胀动力学,并表明高吉诺凝聚在暴胀过程中发生变化。得到的谱指数n_s = 0.95,与原始的跑道暴胀模型一样。因此,额外的场似乎不会改变模型的预测。一个等效的,简化的模型,只有一个单一的领域。

英文摘要:

It is shown that racetrack inflation can be implemented in a moduli stabilisation scenario with a supersymmetric uplifting D-term. The resulting model is completely described by an effective supergravity theory, in contrast to the original racetrack models. We study the inflationary dynamics and show that the gaugino condensates vary during inflation. The resulting spectral index is n_s = 0.95 as in the original racetrack inflation model. Hence extra fields do not appear to alter the predictions of the model. An equivalent, simplified model with just a single field is presented.
