Pure connection formalism for gravity: Recursion relations
Gianluca Delfino, Kirill Krasnov, Carlos Scarinci
In the gauge-theoretic formulation of gravity the cubic vertex becomes simple enough for some graviton scattering amplitudes to be computed using Berends-Giele-type recursion relat…
Graviton scattering amplitudes and Pure Connection Formulation of GR
Gianluca Delfino
We show how the recently introduced "Pure Connection Formulation" of gravity provides a natural framework for approaching the problem of computing graviton scattering amplitudes. I…
Pure connection formalism for gravity: Feynman rules and the graviton-graviton scattering
Gianluca Delfino, Kirill Krasnov, Carlos Scarinci
We continue to develop the pure connection formalism for gravity. We derive the Feynman rules for computing the connection correlation functions, as well as the prescription for ob…
Pure Connection Formalism for Gravity: Linearized Theory
Gianluca Delfino, Kirill Krasnov, Carlos Scarinci
We give a description of gravitons in terms of an SL(2,C) connection field. The gauge-theoretic Lagrangian for gravitons is simpler than the metric one. Moreover, all components of…
Deriving identities for Wigner {nj}-symbols
Gianluca Delfino
We show how a simple and elegant graphical notation can be used to derive the Biedenharn-Elliot identity for the 6j-symbol and we demonstrate how the same technique can be applied…
