An Effective Theory of Initial Conditions in Inflation
The new physics cosmic microwave radiation power spectrum
2014/12/20
We examine the renormalization of an effective theory description of a general initial state set in an isotropically expanding space-time, which is done to understand how to include the effects of new...
N=4 Supersymmetric Yang-Mills theory in soft-collinear effective theory
N=4 Supersymmetric Yang-Mills theory soft-collinear effective theory
2010/12/27
We formulate N=4 supersymmetric Yang-Mills theory in terms of soft-collinear effective theory. The effective Lagrangian in soft-collinear effective theory is developed according to the power counting ...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
Galilean symmetry effective theory inflation
2010/12/23
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory of Inflation, the theory of small perturbations around the inflationary background. This approach allows...

We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
Effective Theory in Spinfoam Cosmology: A First Order LQG-corrected FRW Cosmology and the Stiff Fluid
Effective Theory Spinfoam Cosmology First Order LQG-corrected FRW Cosmology Stiff Fluid
2010/12/20
We present an effective theory of a basic holomorphic spinfoam cosmology peaked on homoge-
neous isotropic metrics. The quantum-corrected Hamiltonian constraint of this effective theory is motivated ...
