The production and decay of a new heavy vector boson, a chromophilic Z^\ensuremath' vector boson, is described. The chromophilic Z^\ensuremath' couples only to two gluons, but its two-body decays are absent, leading to a dominant decay mode of Z^\ensuremath'\ensuremath→qqg. The unusual nature of the interaction predicts a cross-section which grows with m_Z^\ensuremath' for a fixed coupling and an accompanying gluon with a coupling that rises with its energy. We study the ttg decay mode, proposing distinct reconstruction techniques for the observation of an excess and for the measurement of m_Z^\ensuremath'. We estimate the sensitivity of current experimental datasets.
