Coupling gauge theory to spinfoam 3 d quantum gravity

  title={Coupling gauge theory to spinfoam 3 d quantum gravity},
  author={Simone Speziale},
We construct a spinfoam model for Yang-Mills theory coupled to quantum gravity in three dimensional riemannian spacetime. We define the partition function of the coupled system as a power series in g0 G that can be evaluated order by order using grasping rules and the recoupling theory. With respect to previous attempts in the literature, this model assigns the dynamical variables of gravity and Yang-Mills theory to the same simplices of the spinfoam, and it thus provides transition amplitudes… CONTINUE READING
