要旨:
We present a new public package "EFTofPNG" for high precision computation in
the effective field theory of post-Newtonian (PN) Gravity, including spins. We
created this package in view of the timely need to publicly share automated
computation tools, which integrate the various types of physics manifested in
the expected increasing influx of gravitational wave (GW) data. Hence, we
created a free and open source package, which is self-contained, modular,
all-inclusive, and accessible to the classical Gravity community. The
"EFTofPNG" Mathematica package also uses the power of the "xTensor" package,
suited for complicate tensor computation, where our coding also strategically
approaches the generic generation of Feynman contractions, which is universal
to all perturbation theories in physics, by efficiently treating n-point
functions as tensors of rank n. The package currently contains four independent
units, which serve as subsidiaries to the main one. Its final unit serves as a
pipeline chain for the obtainment of the final GW templates, and provides the
full computation of all derivatives and gauge invariant physical observables of
interest. The upcoming "EFTofPNG" package version 1.0 should cover the point
mass sector, and all the spin sectors, up to the fourth PN order, and the
two-loop level. We expect and strongly encourage public development of the
package to improve its efficiency, and to extend it to further PN sectors, and
observables useful for the waveform modeling.
