The statistics of the wavefunction are left unspecified. Using the properties of the Weyl group, we are also able to find Bethe equations. It is notable that the method relies on a certain generalized version of the well-known Yang-Baxter equation. A particular class of non-trivial solutions to this equation emerges naturally.10 pages, 3 figuresMathematical PhysicsHigh Energy Physics - TheoryExactly Solvable and Integrable Systems82B23; 81R12; 70H06Bethe Equations for a g_2 Modeltext
