Abstract
We consider a simple modification of the amplitude defining the dynamics of loop quantum gravity, corresponding to the introduction of the cosmological constant, and possibly related to the extension of the theory recently considered by Fairbairn-Meusburger and Han. We show that, in the context of spinfoam cosmology, this modification yields the de Sitter cosmological solution.
