A toric arrangement is a finite set of hypersurfaces in a complex
torus, every hypersurface being the kernel of a character. In the
present paper we prove that if T(W) is the toric arrangement defined
by the cocharacters lattice of a Weyl group W, then the integer
cohomology of its complement is torsion free.
