无Kahler势的超引力暴胀

Inflation in supergravity without Kahler potential

Shuntaro Aoki, Yusuke Yamada

摘要:

提出了一类新的具有高阶导数项的超引力暴胀模型。在这些模型中,Kähler势不包含暴胀子多重态,但包含超对称导数项。在模型中,暴胀是由一个单一的标量场与一个标准的动力学项和标量势有效地驱动。值得注意的是,所谓的$η$问题在我们的模型中并不存在。

英文摘要:

We propose a new class of inflation models in supergravity with higher derivative terms. In those models, the Kähler potential does not contain the inflaton multiplet, but a supersymmetric derivative term does. In the models, inflation is effectively driven by a single scalar field with a standard kinetic term and a scalar potential. Remarkably, the so-called $η$ problem does not exist in our models.
