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...
Regge kinematics in soft collinear effective theory
Particle kinematics reggeon field emissions reggeon exchange sports area
2014/12/18
We discuss the kinematics of the particles that make up a Reggeon in field theory, using the terminology of the soft collinear effective theory (SCET). Reggeization sums a series of strongly ordered c...
The Time-Reversal- and Parity-Violating Nuclear Potential in Chiral Effective Theory
Time-Reversal Parity-Violating Nuclear Potential
2011/7/20
We derive the parity- and time-reversal-violating nuclear interactions stemming from the QCD theta term and quark/gluon operators of effective dimension 6: quark electric dipole moments, quark and glu...
We work out an effective theory of accelerated expansion to describe general phenomena of inflation and acceleration (dark energy) in the Universe. Our aim is to determine from theoretical grounds, in...
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 ...

2010/12/23
In the author's paper (Phys.Rev. D80, 041901(R) (2009)), the integrable structure of the symmetry reduced bosonic dynamics in the low energy heterotic string effective theory was presented. In that p...

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...

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 ...
Effective theory for deformed nuclei

2011/1/7
Techniques from effective field theory are applied to nuclear rotation. This approach exploits the spontaneous breaking of rotational symmetry and the separation of scale between low-energy Nambu-Gold...
