Feynman-like Rules for Calculating n-Point Correlators of the Primordial Curvature Perturbation
ing n-Point Correlators Primordial Curvature Perturbation
2011/10/10
A diagrammatic approach to calculate n-point correlators of the primordial curvature perturbation \zeta was developed a few years ago following the spirit of the Feynman rules in Quantum Field Theory....
Waterfall field in hybrid inflation and curvature perturbation
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

We study carefully the contribution of the waterfall field to the curvature perturbation at the end of hybrid inflation. In particular we clarify the parameter dependence analytically under reasonable...
Perturbation of heliosynchronous orbits in stable Kaluza-Klein theory
heliosynchronous orbits stable Kaluza-Klein theory
2010/3/8
Although the methods and techniques have been greatly improved since the late nineteenth century, the precision on the measurement of the gravitational constant G does not exceed 1 part in 1000. Intri...
