Phys. Rev. D 63, 084021 (2001) [9 pages]BF actions for the Husain-Kuchař modelReceived 7 November 2000; published 27 March 2001 We show that the Husain-Kuchař model can be described in the framework of BF theories. This is a first step towards its quantization by standard perturbative quantum field theory techniques or the spin-foam formalism introduced in the space-time description of general relativity and other diff-invariant theories. The actions that we will consider are similar to the ones describing the BF-Yang-Mills model and some mass generating mechanisms for gauge fields. We will also discuss the role of diffeomorphisms in the new formulations that we propose. © 2001 The American Physical Society URL:
