Constraint on the Higgs-Dilaton Potential via Warm Inflation in Two-Time Physics

Vo Quoc Phong (Department of Theoretical Physics, University of Science, Ho Chi Minh City 700000, Vietnam; Vietnam National University, Ho Chi Minh City 700000, Vietnam) ; Ngo Phuc Duc Loc (Department of Theoretical Physics, University of Science, Ho Chi Minh City 700000, Vietnam; Vietnam National University, Ho Chi Minh City 700000, Vietnam)

Within the SP2,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 ~ϕ4. From that consideration, we derive the range of parameters for the Higgs-Dilaton potential, the coupling constant between Higgs and Dilaton (α) is larger than 0.0053 and the mass of Dilaton is smaller than 107 GeV. Therefore, the 2T model indirectly suggests that extra dimension can also be a source of inflation.
