支持向零宇宙学常数态跃迁的对称性

Symmetry Supporting a Transition to Zero Cosmological Constant State

E. I. Guendelman, A. B. Kaganovich

摘要:

在一些以前的出版物中,我们证明了两个措施场论(TMT)能够解决旧的宇宙学常数(CC)的问题,避免了温伯格的不去CC定理,并与此TMT同意爱因斯坦的广义相对论的所有测试,并允许通货膨胀的情况。本文的分析表明,存在一个内在的对称性TMT出现在$Λ=0$基态。这种对称性包含一个子群的反射的度量$g_{μν}\to -g_{μν}$最近研究了一些作者的对称强加零CC。我们表明,实现这一想法在TMT是免费的微调,并没有典型的其他方法的问题。

英文摘要:

In a number of previous publications we demonstrated that the Two Measures Field Theory (TMT) enables to resolve the old cosmological constant (CC) problem avoiding the Weinberg's no-go CC theorem and together with this TMT agrees with all tests of the Einstein's general relativity and allows inflationary scenarios. Analysis performed in the present paper shows that there exists an intrinsic symmetry of TMT which emerges in the $Λ=0$ ground state. This symmetry contains a subgroup of reflections of the metric $g_{μν}\to -g_{μν}$ studied recently by a number of authors as the symmetry imposing zero CC. We show that realization of this idea in TMT is free of fine tuning and has no problems typical to other approaches.
