Gravity and Yang-Mills Amplitude Relations
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
Using only general features of the S-matrix and quantum field theory, we prove by induction the Kawai-Lewellen-Tye relations that link products of gauge theory amplitudes to gravit…
Gravitino Interactions from Yang-Mills Theory
N. E. J. Bjerrum-Bohr, Oluf Tang Engelund
We fabricate gravitino vertex interactions using as only input on-shell Yang-Mills amplitudes and the Kawai-Lewellen-Tye gauge theory / gravity relations. A useful result of this a…
String theory and the KLT-relations between gravity and gauge theory including external matter
N. E. J. Bjerrum-Bohr, K. Risager
We consider the Kawai-Lewellen-Tye (KLT) factorizations of gravity scalar-leg amplitudes into products of scalar-leg Yang-Mills amplitudes. We check and examine the factorizations…
Quantum gravity at a large number of dimensions
N. E. J. Bjerrum-Bohr
We consider the large- limit of Einstein gravity. It is observed that a consistent leading large- graph limit exists, and that it is built up by a subclass of planar diagrams…
Generalized string theory mapping relations between gravity and gauge theory
N. E. J. Bjerrum-Bohr
A previous study of the Kawai, Lewellen and Tye (KLT) relations between gravity and gauge theories, imposed by the relationship of closed and open strings, are here extended in the…
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…
