Electroweak Phase Transition, Gravitational Waves and Dark Matter in Two Scalar Singlet Extension of The Standard Model
Vahid Reza Shajiee, Ali Tofighi
In this paper, the electroweak phase transition, the gravitational waves and the dark matter issues are investigated in two scalar singlet extension of the standard model. The dete…
Mass of the Stabilized Radion in the Limit of Finite Quartic Coupling
Ali Tofighi, Vahid Reza Shajiee
We present an exact treatment of the modulus stabilization condition with the general boundary conditions of the bulk scalar field in the Randall-Sundrum model. We find analytical…
Strong electroweak phase transition in a model with extended scalar sector
Mina Saeedhoseini, Ali Tofighi
In this paper we consider an extension of the Standard Model(SM) with additional gauge singlets which exhibits a strong first order phase transition. Due to this first order phase…
Localization of massive and massless fermion on two field brane
A. Farokhtabar, A. Tofighi
In this paper we study fermion localization and resonances on a special type of braneworld model supporting brane splitting. In such models one can construct multi-wall branes whic…
Phase transition in multi-scalar-singlet extensions of the Standard Model
A. Tofighi, O. N. Ghodsi, M. Saeedhoseini
We propose a generalization of the Standard Model (SM) by adding two real gaugesinglets S1, S2. The field S1 will improve the strength of the electroweak phase transition (EWPT). I…
Vacuum Expectation Value Profiles of the Bulk Scalar Field in the Generalized Randall-Sundrum Model
A. Tofighi, M. Moazzen, A. Farokhtabar
In the generalized Randall-Sundrum warped brane-world model the cosmological constant induced on the visible brane can be positive or negative. In this paper we investigate profile…
Phase structure of the generalized two dimensional Yang-Mills theories on sphere
M. Alimohammadi, A. Tofighi
We find a general expression for the free energy of generalized 2D Yang-Mills theories in the strong () region at large . We also show that in this region,…
