摘要：

考虑一个新的暴胀模型，其中反对称张量场$A_{νρσ}$及其四种形式的场强$F_{μνρσ}=4\partial_{[μ} A_{νρσ]}$耦合到标准模型的标量扇区和Ricci标量$\mathcal{R}$ .四种形式的场导致了对Higgs自耦合常数、宇宙学常数和非最小耦合常数的修正，这导致了对暴胀子势的修正。我们还表明，在四种形式的引力相互作用的存在下，不需要希格斯引力耦合，但仍然可以产生适量的密度扰动的通货膨胀。

英文摘要：

We consider a new inflationary model in which an antisymmetric tensor field $A_{νρσ}$ and its four-form field strength $F_{μνρσ}=4\partial_{[μ} A_{νρσ]}$ are coupled to the scalar sector of the standard model and to the Ricci scalar $\mathcal{R}$. The four-form field induces modifications to the Higgs self-coupling constant, the cosmological constant, and the non-minimal coupling constant, which results in the modification to the inflaton potential. We also show that there is no need for the Higgs-gravity coupling in the presence of four-form-gravity interaction, but still can produce the right amount of density perturbation for inflation.
