We consider a new inflationary model in which an antisymmetric tensor field A _νρσ and its four-form field strength F _μνρσ = 4∂_[μ A _νρσ] are coupled to the scalar sector of the standard model and to the Ricci scalar . 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.

具有四形式耦合的希格斯膨胀

我们考虑一个新的暴胀模型，其中反对称张量场A _νρσ及其四形式场强F _μνρσ = 4∂ _{[ μ} A _{νρσ ]}耦合到标准模型的标量扇区和 Ricci 标量。四形式场引起希格斯自耦合常数、宇宙学常数和非最小耦合常数的修改，从而导致对暴胀子势的修改。我们还表明，在存在四形式重力相互作用的情况下，不需要希格斯引力耦合，但仍然可以产生适量的密度扰动以进行膨胀。
