« Compact binary dynamics in the effective field theory approach »

Stefano Foffa
Dept. Physique Théorique, Univ. Genève (Genève, Suisse)

In the first part of the talk, I will review some aspects of the
EFT approach to the two-body bound state in General Relativity.
Then I will focus on the logarithmic terms in the gaude-invariant Energy
function. Such logarithms derive from non-local
contributions related to the interlpay between radiation zone and near
zone physics and, by exploiting several apparently unrelated properties
of the binary system, it is possible to compute them at very high
post-Newtonian order.
