Review of new physics effects in $t\bar{t}$ production

Abstract

\n Both CDF and DØ report a forward–backward asymmetry in $t\\bar{t}$ production that is above the standard model prediction. We review new physics models that can give a large forward backward asymmetry in $t\\bar{t}$ production at the Tevatron and the constraints these models face from searches for dijet resonances and contact interactions, from flavor physics and the $t\\bar{t}$ cross section. Expected signals at the LHC are also reviewed.\n
