Cosmological constraints on Lorentz invariance violation in the neutrino sector
Zong-Kuan Guo, Qing-Guo Huang, Rong-Gen Cai +1
We derive the Boltzmann equation in the synchronous gauge for massive neutrinos with a deformed dispersion relation. Combining the 7-year WMAP data with lower-redshift measurements…

Primordial power spectrum versus extension parameters beyond the standard model
Zong-Kuan Guo, Yuan-Zhong Zhang
We reconstruct the shape of the primordial power spectrum of curvature perturbations in extended cosmological models, including addition of massive neutrinos, extra relativistic sp…
