Description
We consider the elementary radiative-correction terms in loop quantum gravity. These are a two-vertex 'elementary bubble' and a five-vertex 'ball'; they correspond to the one-loop self-energy and the one-loop vertex correction of ordinary quantum field theory. We compute their naive degree of (infrared) divergence.
