论文摘要
我们研究了在轴突驱动的通货膨胀期间，在经典SU（2）量规场的背景下，大规模载体样费物的产生和反射。我们证明，由于与费米相互作用的相互作用，所有紫外线差异可以通过轴承波函数的重新归一化和量规耦合来吸收。 Fermion-Axion相互作用在对称性要求下在无质量极限中消失的影响。对于非常庞大的费米，在轴，仪表场和重力场之间诱导接触相互作用。在这个巨大的极限中，我们发现通常诱导了通常的轴轴测场相互作用，但是，此外，我们观察到了轴突自相互作用的外观，以及与爱因斯坦张量的轴突的动力学编织。这些新的轴突衍生物相互作用为建立模型和现象学带来了有趣的机会。
We study the production and backreaction of massive vector-like fermions in the background of a classical SU(2) gauge field during axion-driven inflation. We demonstrate all ultraviolet divergences due to the interactions with the fermions can be absorbed by renormalization of the axion wavefunction and the gauge coupling. The effects of the fermion-axion interaction vanish in the massless limit as required by symmetry. For very massive fermions, contact interactions are induced between the axion, the gauge field and the gravitational field. In this massive limit, we find the usual axion-gauge field interactions are induced, however, in addition we observe the appearance of axion self-interactions, as well as kinetic braiding of the axion with the Einstein tensor. These new axion derivative interactions present intriguing opportunities for model building and phenomenology.
