In models of maximal flavor violation (MxFV) suggested in [S. Bar-Shalom and A. Rajaraman, Phys. Rev. D 77, 095011 (2008).] there is at least one new scalar {phi}{sub FV} which couples to the quarks via {phi}{sub FV}q{sub i}q{sub j}{proportional_to}{xi}{sub ij} where {xi}{sub i3},{xi}{sub 3i}{approx}V{sub tb} for i=1, 2 and {xi}{sub 33}{approx}V{sub td} and V is the CKM matrix. In this article, we explore the potential phenomenological implications of MxFV for collider experiments. We study MxFV signals of same-sign leptons from same-sign top-quark pair production at the Tevatron and at the LHC. We show that the current Tevatron data set has strong sensitivity to this signature, for which there are no current limits. For example, if m{sub {phi}{sub FV}}{approx}200 GeV and the MxFV coupling {xi} has a natural value of {approx}1, we expect {approx}12 MxFV events to survive a selection requiring a pair of same-sign leptons, a tagged b-jet and missing transverse energy, over a background of approximately 4-5 events.
