引力对称破缺中的暗物质和暗能量

Dark Matter and Dark Energy from Gravitational Symmetry Breaking

A. Fuzfa, J. -M. Alimi

摘要:

基于伪Nambu-Goldstone暗物质(DM)粒子质量变化引起的等效原理的松弛,建立了一个整体U(1)对称性的引力对称性破缺(GSB)机制.这GSB过程中所描述的修改后的宇宙学收敛机制的异常加权能量(AWE)假说先前介绍的作者。几个显着的约束,从遥远的超新星的哈勃图导出,特别是在显式和引力对称性破缺的能量尺度的模型。然后,我们简要介绍了一些后果中微子质量时,这一机制被应用到轻子数对称性破缺的特殊情况。

英文摘要:

We build a mechanism of gravitational symmetry breaking (GSB) of a global U(1) symmetry based on the relaxation of the equivalence principle due to the mass variation of pseudo Nambu-Goldstone dark matter (DM) particles. This GSB process is described by the modified cosmological convergence mechanism of the Abnormally Weighting Energy (AWE) Hypothesis previously introduced by the authors. Several remarkable constraints from the Hubble diagram of far-away supernovae are derived, notably on the explicit and gravitational symmetry breaking energy scales of the model. We then briefly present some consequences on neutrino masses when this mechanism is applied to the particular case of the breaking of lepton number symmetry.
