Fitting the Constitution SNIa Data with Redshift Binned Parameterization Method
Qing-Guo Huang, Miao Li, Xiao-Dong Li +1
In this work, we explore the cosmological consequences of the recently released Constitution sample of 397 Type Ia supernovae (SNIa). By revisiting the Chevallier-Polarski-Linder (…
The Trispectrum in the Multi-brid Inflation
Qing-Guo Huang
The trispectrum is at least as important as the bispectrum and its size can be characterized by two parameters and . In this short paper, we focus on the Multi-bri…
Field Theory at a Lifshitz Point
Bin Chen, Qing-Guo Huang
We construct the general renormalizable actions for the scalar field and the gauge field at a Lifshitz point characterized by the dynamical critical exponent . The Lorentz invar…
A geometric description of the non-Gaussianity generated at the end of multi-field inflation
Qing-Guo Huang
In this paper we mainly focus on the curvature perturbation generated at the end of multi-field inflation, such as the multi-brid inflation. Since the curvature perturbation is pro…
The Curvature Perturbation in the Axion-type Curvaton Model
Pravabati Chingangbam, Qing-Guo Huang
We study the axion-type curvaton model, with emphasis on the large field regime where analytic results are very difficult to obtain. We evaluate the tensor-scalar ratio using W…
