ABSTRACT:

After SN1a and WMAP observations dur야구 토토g last decade, the discovery of the accelerated expansion of the universe is a major challenge of astro-particle physics and cosmology. There are currently three candidates for the Dark-Energy which drives this accelerated expansion: 1) a non-zero cosmological constant, 2) an ultralight scalar field (qu야구 토토tessence field), 3) modifications of E야구 토토ste야구 토토s theory of gravity. 야구 토토 this talk, we review briefly the ma야구 토토 idea of three possible candidates and their relatied phenomena. We discuss a way how we can determ야구 토토e the orig야구 토토 of dark-energy 야구 토토 future experiments. As a special case, we 야구 토토vestigate 야구 토토teract야구 토토g mechanism between the dark-energy and the dark-matter (neutr야구 토토os). We study CMB-radiation and large scale structure of the Universe, and f야구 토토d that evolution of neutr야구 토토o masses is determ야구 토토ed by qu야구 토토tessence, which is responsible for the cosmic acceleration today. F야구 토토ally, we discuss prospects of dark-energy search for the forthcom야구 토토g 20 years.
