Scalar field localization on a brane with cosmological constant
نویسندگان
چکیده
We address the localization of a scalar field, whose bulk-mass M is considered in a wide range including the tachyonic region, on a three-brane. The brane with non-zero cosmological constant λ is embedded in five dimensional bulk space. We find in this case that the trapped scalar could have mass m which has an upper bound and expressed as m = m20 + αM 2 ≤ β|λ| with the calculable numbers m20, α, β. We point out that this result would be important to study the stability of the brane and also the cosmological problems based on the brane-world. [email protected] [email protected]

The massive Elko spinor field in the de Sitter braneworld model
The Elko spinor field is a spin 1/2 fermionic quantum field with a mass dimension introduced as a candidate of dark matter. In this work, we study the localization of Elko fields on a de Sitter thick brane constructed by a canonical or phantom scalar field. By presenting the mass-independent potentials of Kaluza-Klein (KK) modes in the corresponding Schrödinger equations, it is shown that the E...
متن کاملVacuum Energy Density and Cosmological Constant in dS Brane World
We discuss the vacuum energy density and the cosmological constant of dS5 brane world with a dilaton field. It is shown that a stable AdS4 brane can be constructed and gravity localization can be realized. An explicit relation between the dS bulk cosmological constant and the brane cosmological constant is obtained. The discrete mass spectrum of the massive scalar field in the AdS4 brane is use...
متن کاملBrane gravity , massless bulk scalar and self - tuning of the cosmological constant ( a )
We show that a self-tuning mechanism of the cosmological constant could work in 5D non-compact space-time with a Z 2 symmetry in the presence of a massless scalar field. The standard model matter fields live only on the 4D brane. The change of vacuum energy on the brane (brane cosmological constant) by, for instance, electroweak and QCD phase transitions, just gives rise to dynamical shifts of ...
متن کاملLocally Localized Gravity and Geometric Transitions
In this paper we analyze the local localization of gravity in AdS4 thick brane embedded in AdS5 space. The 3-brane is modelled by domain wall solution of a theory with a bulk scalar field coupled to five-dimensional gravity. In addition to small four-dimensional cosmological constant, the vacuum expectation value (vev) of the scalar field controls the emergence of a localized four-dimensional q...
متن کاملScalar potential from de Sitter brane in 5D and effective cosmological constant
We derive the scalar potential in zero mode effective action arising from a de Sitter brane embedded in five dimensions with bulk cosmological constant Λ. The scalar potential for a scalar field canonically normalized is given by the sum of exponential potentials. In the case of Λ = 0 and Λ > 0, we point out that the scalar potential has a unstable local maximum at the origin and exponentially ...
