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

TL;DR

This paper explores how the Two-Time Physics model with $SP(2,R)$ symmetry constrains the Higgs-Dilaton potential within warm inflation, indicating that extra dimensions may influence inflationary dynamics.

Contribution

It derives parameter constraints for the Higgs-Dilaton potential in the 2T model, linking extra dimensions to inflationary scenarios.

Findings

Coupling constant $ extgreater 0.0053$ between Higgs and Dilaton

Dilaton mass less than $10^{-7}$ GeV

Extra dimensions can serve as a source of inflation

Abstract

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 $\sim\phi^4$. From that consideration, we derive the range of parameters for the Higgs-Dilaton potential, the coupling constant between Higgs and Dialton ($\alpha$) 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.
