Improved automated lattice perturbation theory in background field gauge
Improved automated lattice perturbation theory background field gauge
2011/1/6
We present an algorithm to automatically derive Feynman rules for lattice perturbation theory in background field gauge. Vertices with an arbitrary number of both background and quantum legs can be de...

Staggered chiral perturbation theory in the two-flavor case and SU(2) analysis of the MILC data
Staggered chiral perturbation theory two-flavor case
2011/1/6
In the light pseudoscalar sector, we study rooted staggered chiral perturbation theory in the two-flavor case. The pion mass and decay constant are calculated through NLO for a partially-quenched theo...

Second-order Gauge-invariant Cosmological Perturbation Theory: Current Status
Gauge-invariant Current Status
2010/3/17
The current status of the recent developments of the second-order gauge-invariant cosmological perturbation theory is reviewed. To show the essence of this perturbation theory, we concentrate only on ...
