  We investigate the production of beyond-the-standard-model color-sextet
vector bosons at the Large Hadron Collider and their decay into a pair of
same-sign top quarks. We demonstrate that the energy of the charged lepton from
the top quark semi-leptonic decay serves as a good measure of the top-quark
polarization, which, in turn determines the quantum numbers of the boson and
distinguishes vector bosons from scalars.
