Quantum Gravitational Corrections to the Nonrelativistic Scattering Potential of Two Masses
N. E. J Bjerrum-Bohr, John F. Donoghue, Barry R. Holstein
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 rul…
K -> pi pi Electroweak Penguins in the Chiral Limit
V. Cirigliano, J. F. Donoghue, E. Golowich +1
We report on dispersive and finite energy sum rule analyses of the electroweak penguin matrix elements < (pi pi) | Q_{7,8} | K > in the chiral limit. We accomplish the correct pert…
Random values of the physical parameters
John F. Donoghue
I briefly describe two motivations, two mechanisms and two possible tests of the hypothesis that the physical parameters of the ground state of a theory can vary in different regio…
Infrared behavior of graviton-graviton scattering
J. F. Donoghue, T. Torma
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(E^4) with onl…
