Query: q-Deformation of Lorentzian spin foam models   We construct and analyse a quantum deformation of the Lorentzian EPRL model.
The model is based on the representation theory of the quantum Lorentz group
with real deformation parameter. We give a definition of the quantum EPRL
intertwiner, study its convergence and braiding properties and construct an
amplitude for the four-simplexes. We find that the resulting model is finite.
