  The production of heavy flavor quark pairs, including top-anti-top, at the
LHC proceeds primarily through gluon fusion. The correlation between the gluon
spins affects various spin correlations between the produced quark and
anti-quark. Both single spin asymmetries and double correlations of the quark
pair spins will be manifest in the subsequent hadronization and decay
distributions. For top pairs this is most pronounced. Dilepton, single lepton,
and purely hadronic top pair decay channels allow for the extraction of gluon
spin information as well as providing a window into possible interactions
Beyond the Standard Model. Spin related asymmetries and polarizations will be
presented. The implications for experimental determination will be discussed.
