Mass and rapidity dependent top quark forward-backward asymmetry in the
effective Lagrangian approach    [PDF]

Dong-Won Jung, P. Ko, Jae Sik Lee

We study the invariant mass and rapidity dependent top quark forward-backward asymmetry from the effective Lagrangian viewpoint. The Wilson coefficients are constrained by the experimental observations and the concrete models that reproduce the low energy effective Lagaragians are considered. Some of them are disfavored and others relatively favored. For each cases, we estimate the appropriacy of the effective Lagrangian approach.
