The (\\bar{u} gamma_mu gamma^5 T^a u)(\\bar{t} gamma^mu gamma^5 T^a t) operator modifies the large M_{t\\bar{t}} forward-backward asymmetry, and can account for the recent CDF measurement. The (\\bar{u} gamma_mu T^a u)(\\bar{t} gamma^mu T^a t) operator modifies the differential cross section, but cannot enhance the cross section of ultra-massive boosted jets by more than 60%.
