| Research Abstract |
We developed a novel method for computing galaxy power spectrum in a mixed dark matter (cold dark matter plus finite-mass neutrinos) model, taking into account effects of nonlinear clustering and nonlinear, scale-dependent galaxy bias. By comparing the model predictions to the SDSS galaxy power spectrum, we succeeded in deriving the upper limit on the sum of three-flavor neutrinos given as M_<ν,tot><0.81eV (95.%C.L.).
