A new cosmological constant model
We propose a new cosmological model with a time-dependent cosmological constant (Λ ∝ 1/t), which starting at the Planck time as ΛP l ∼ M P l, evolves to the present-day allowed value of Λ0 ∼ 10M P l. This scenario is supported by non-critical string theory considerations. We compute the age of the Universe and the time-dependence of the scale factor in this model, and find general agreement wit...
متن کاملA New Cosmological Paradigm: the Cosmological Constant and Dark Matter
The Standard Cosmological Model of the 1980’s is no more. I describe the definitive evidence that the density of matter is insufficient to result in a flat universe, as well as the mounting evidence that the cosmological constant is not zero. I finally discuss the implications of these results for particle physics and direct searches for non-baryonic dark matter, and demonstrate that the new ne...
متن کاملCosmological Perturbations and the Running Cosmological Constant Model
We study the matter density fluctuations in the running cosmological constant (RCC) model using linear perturbations in the longitudinal gauge. Using this observable we calculate the growth rate of structures and the matter power spectrum, and compare them with the SDSS data and other available data of the linear growth rate. The distribution of collapsed structures may also constraints models ...
متن کاملStandard Model Parameters and the Cosmological Constant ∗
Simple functional relations amongst standard model couplings, including gravitional, are conjectured. Possible implications for cosmology and future theory are discussed. Submitted to The Physical Review. ∗Work supported by Department of Energy contract DE–AC03–76SF00515.
متن کاملProposal for a Constant Cosmological Constant
It is proposed that the apparent positive acceleration of the cosmological scale factor is due to the vacuum energy of an incomplete chiral phase transition in a hidden SU(2) sector. Constraints from primordial nucleosynthesis imply that the present metastable phase is in a substantially supercooled state. It is argued that massless chiral condensates can substantially enhance the possibility o...
