| 英文摘要 | With the latest astronomical data including cosmic microwave background (WMAP three-year, CBI, ACBAR, VSA), Type Ia Supernovae ('gold sample'), galaxy clustering (SDSS 3D matter power, Lyman-alpha forest and baryon acoustic oscillating (BAO)), we make a global fitting to constrain the mass varying neutrinos. We find that the parameter delta, denoting time evolving of neutrino mass, is weakly constrained and the neutrino mass limit today can be relaxed at least by a factor of two. Adding data of 0v2 beta decay of the Heidelberg-Moscow experiment to our analysis, we find that d can be constrained tightly and mass varying neutrinos are favored at about 99.7% confidence level. |
