On Cancellations of Ultraviolet Divergences in Supergravity Amplitudes
N. E. J. Bjerrum-Bohr, Pierre Vanhove
Concrete calculations have pointed out that amplitudes in perturbative gravity exhibit unanticipated cancellations taming their ultraviolet behaviour independently of supersymmetry…
Explicit Cancellation of Triangles in One-loop Gravity Amplitudes
N. E. J. Bjerrum-Bohr, Pierre Vanhove
We analyse one-loop graviton amplitudes in the field theory limit of a genus-one string theory computation. The considered amplitudes can be dimensionally reduced to lower dimensio…
Analytic Structure of Three-Mass Triangle Coefficients
N. E. J. Bjerrum-Bohr, David C. Dunbar, Warren B. Perkins
``Three-mass triangles'' are a class of integral functions appearing in one-loop gauge theory amplitudes. We discuss how the complex analytic properties and singularity structures…
Quantum gravity, effective fields and string theory
Niels Emil Jannik Bjerrum-Bohr
We look at the various aspects of treating general relativity as a quantum theory. It is briefly studied how to consistently quantize general relativity as an effective field theor…
