两时间物理中Higgs-Dilaton势的热膨胀约束

Constraint on the Higgs-Dilaton potential via Warm inflation in Two-Time Physics

Vo Quoc Phong, Ngo Phuc Duc Loc

摘要:

在$SP(2,R)$对称性中,二时间模型(2 T模型)有六个维度,其中两个维度是时间和可被识别为暖暴胀情景中的暴胀子的惠子场,其势形式为$\simϕ^4$。在此基础上,我们导出了Higgs-Dilaton势的参数范围,Higgs与Dialton的耦合常数($α$)大于$0.0053$,Dilaton的质量小于$10^{-7}$ GeV。因此,2 T模型间接表明额外维度也可能是通货膨胀的一个来源。

英文摘要:

Within the $SP(2,R)$ symmetry, the Two-time model (2T model) has six dimensions with two dimensions of time and the dilaton field that can be identified as inflaton in a warm inflation scenario with potential of the form $\simϕ^4$. From that consideration, we derive the range of parameters for the Higgs-Dilaton potential, the coupling constant between Higgs and Dialton ($α$) is larger than $0.0053$ and the mass of Dilaton is smaller than $10^{-7}$ GeV. Therefore, the 2T-model indirectly suggests that extra-dimension can also be a source of inflation.
