Title: Parametrised group field theories and quantum gravity transition amplitudes
Abstract: We describe a generalisation of the group field theory formalism to include extra variables with the interpretation of proper time, and an action that contains derivative kinetic terms; we show how to construct the Feynman expansion of the field theory and how to obtain both causal and a-causal spin foam amplitudes from this generalised formalism.
