超对称变质量中微子模型中的假真空

False Vacuum in the Supersymmetric Mass Varying Neutrinos Model

Ryo Takahashi, Morimitsu Tanimoto

摘要:

本文详细分析了超对称变质量中微子模型中标量势的真空结构。模型中观测到的暗能量密度与假真空能量一致,而$(10^{-3}eV)^4$阶暗能量标度则由引力抑制的超对称破缺标度$F({TeV})^2/M_{Pl}$来理解。为了使模型成立,中微子的真空期望值必须很小。模型还讨论了超粒子衰变为加速子和不育中微子的过程。

英文摘要:

We present detailed analyses of the vacuum structure of the scalar potential in a supersymmetric Mass Varying Neutrinos model. The observed dark energy density is identified with false vacuum energy and the dark energy scale of order $(10^{-3}eV)^4$ is understood by gravitationally suppressed supersymmetry breaking scale, $F({TeV})^2/M_{Pl}$, in the model. The vacuum expectation values of sneutrinos should be tiny in order that the model works. Some decay processes of superparticles into acceleron and sterile neutrino are also discussed in the model.
