Description
In models of maximal flavor violation (MxFV) there is at least one new scalar $\Phi_{FV}$ which couples to the quarks via $\Phi_{FV} q_i q_j \propto \xi_{ij}$ where $\xi_{i3},\xi_{3i} \sim V_{tb}$ for $i = 1,2$ and $\xi_{33} \sim V_{td}$ and $V$ is the CKM matrix. We study MxFV signals of same-sign leptons from same-sign top-quark pair production at CDF. We search for a pair of same-sign leptons, a tagged $b$-jet and missing transverse energy, and set limits on $m_{\Phi_{FV}}$ and the MxFV coupling $\xi$.
