Searching for Top Flavor Violating Resonances

Gresham, Moira I., Kim, Ian-Woo, Zurek, Kathryn M.

Understand

We study new top flavor violating resonances that are singly produced in association with a top at the LHC.

Such top flavor violating states could be responsible for the Tevatron top forward-backward asymmetry.
Since top flavor violating states can directly decay to a top (or anti-top) and jet, and are produced in conjunction with another (oppositely charged) top, the direct signature of such states is a t j (or tbar j) resonance in t tbar j events.
In general, these states can be very light and have O(1) couplings to the top sector so that they are copiously produced.
