Quasi-Single Field Inflation and Non-Gaussianities
Xingang Chen, Yi Wang
In quasi-single field inflation models, massive isocurvature modes, that are coupled to the inflaton and have mass of order the Hubble parameter, can have nontrivial impacts on den…
Large non-Gaussianities with Intermediate Shapes from Quasi-Single Field Inflation
Xingang Chen, Yi Wang
We study the slow-roll inflation models, where the inflaton slow-rolls along a trajectory whose orthogonal directions are lifted by potentials with masses of order the Hubble param…
Search for Dimuon Decays of a Light Scalar Boson in Radiative Transitions Upsilon -> gamma A0
The BABAR Collaboration, B. Aubert
We search for evidence of a light scalar boson in the radiative decays of the Upsilon(2S) and Upsilon(3S) resonances: Upsilon(2S,3S)-> gamma A0, A0 -> mu^+ mu^-. Such a particle ap…
Large Primordial Trispectra in General Single Field Inflation
Xingang Chen, Bin Hu, Min-xin Huang +2
We compute the large scalar four-point correlation functions in general single field inflation models, where the inflaton Lagrangian is an arbitrary function of the inflaton and it…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
Non-Gaussianity as a Probe of the Physics of the Primordial Universe and the Astrophysics of the Low Redshift Universe
E. Komatsu, N. Afshordi, N. Bartolo +58
A new and powerful probe of the origin and evolution of structures in the Universe has emerged and been actively developed over the last decade. In the coming decade, non-Gaussiani…
