I describe the treatment of gravity as a quantum effective field theory. This allows a natural separation of the (known) low energy quantum effects from the (unknown) high energy contributions. Within this framework, gravity is a well behaved quantum field theory at ordinary energies. In studying the class of quantum corrections at low energy, the dominant… (More)

This is a pedagogical introduction to the treatment of general relativity as a quantum effective field theory. Gravity fits nicely into the effective field theory description and forms a good quantum theory at ordinary energies. Lectures presented at the Advanced School on Effective Theories, Almunecar, Spain June 1995 (to be published in the proceedings).… (More)

I argue that the leading quantum corrections, in powers of the energy or inverse powers of the distance, may be computed in quantum gravity through knowledge of only the low energy structure of the theory. As an example, I calculate the leading quantum corrections to the Newtonian gravitational potential.

We consider the scattering of lightlike matter in the presence of a heavy scalar object (such as the Sun or a Schwarzschild black hole). By treating general relativity as an effective field theory we directly compute the nonanalytic components of the one-loop gravitational amplitude for the scattering of massless scalars or photons from an external massive… (More)

We examine the corrections to the lowest order gravitational interactions of massive particles arising from gravitational radiative corrections. We show how the masslessness of the graviton and the gravitational self interactions imply the presence of nonanalytic pieces ∼ √ −q2,∼ q ln−q2, etc. in the form factors of the energy-momentum tensor and that these… (More)

22 In this paper the realized niche of the Snowy Plover (Charadrius alexandrinus), a 23 primarily resident Florida shorebird, is described as a function of the scenopoetic and 24 bionomic variables at the nest-, landscape-, and regional-scale. We identified some pos25 sible geomorphological controls that influence nest-site selection and survival using data… (More)

The quantum effective theory of general relativity, independent of the eventual full theory at high energy, expresses graviton-graviton scattering at one loop order O ( E4 ) with only one parameter, Newton’s constant. Dunbar and Norridge have calculated the one loop amplitude using string based techniques. We complete the calculation by showing that the 1… (More)

We consider scattering in quantum gravity and derive long-range classical and quantum contributions to the scattering of light-like bosons and fermions (spin-0, spin1 2 , spin-1) from an external massive scalar field, such as the Sun or a black hole. This is achieved by treating general relativity as an effective field theory and identifying the… (More)

We perform a finite energy sum rule analysis of the flavor ud two-point VA current correlator, ∆Π(Q2). The analysis, which is performed using both the ALEPH and OPAL databases for the V-A spectral function, ∆ρ, allows us to extract the dimension six V-A OPE coefficient, a6, which is related to the matrix element of the electroweak penguin operator, Q8, by… (More)

We treat general relativity as an effective field theory, obtaining the full nonanalytic component of the scattering matrix potential to one-loop order. The lowest order vertex rules for the resulting effective field theory are presented and the one-loop diagrams which yield the leading nonrelativistic post-Newtonian and quantum corrections to the… (More)
