New results at 3PN via an effective field theory of gravity
NRGR, an Effective Field Theory approach to gravity, has emerged as a
powerful tool to systematically compute higher order corrections in the
Post-Newtonian expansion. Here we discuss in somehow more detail the recently
reported new results for the spin-spin gravitational potential at third
Post-Newtonian order.Comment: 4 pages, talk at the 11th Marcel Grossmann meeting, Berlin, july 200
Reasoning by analogy: attempts to solve the cosmological constant paradox

Analytic approximations, perturbation theory, effective field theory methods and their applications
We summarize the parallel session B4: 'Analytic approximations, perturbation
theory effective field theory methods and their applications' and the joint
session B2/B4: 'Approximate solutions to Einstein equations: Methods and
Applications', of the GR20 & Amaldi10 conference in Warsaw, July 2013. The
contributed talks reported significant advances on various areas of research in
gravity.Comment: 15 pages. Contribution to the Proceedings of GR20 - Amaldi1
