description

Models of maximal flavor violation (MxFV) in elementary particle physics may contain at least one new scalar SU(2) doublet field {phi}{sub FV}=({eta}{sup 0},{eta}{sup +}) that couples the first and third generation quarks (q{sub 1}, q{sub 3}) via a Lagrangian term L{sub FV}={xi}{sub 13}{phi}{sub FV}q{sub 1}q{sub 3}. These models have a distinctive signature of same-charge top-quark pairs and evade flavor-changing limits from meson mixing measurements. Data corresponding to 2 fb{sup -1} collected by the Collider Dectector at Fermilab II detector in pp collisions at {radical}(s)=1.96 TeV are analyzed for evidence of the MxFV signature. For a neutral scalar {eta}{sup 0} with m{sub {eta}{sup 0}}=200 GeV/c{sup 2} and coupling {xi}{sub 13}=1, {approx}11 signal events are expected over a background of 2.1{+-}1.8 events. Three events are observed in the data, consistent with background expectations, and limits are set on the coupling {xi}{sub 13} for m{sub {eta}{sup 0}}=180-300 GeV/c{sup 2}.
