The authors' main claim We study the prospects for measuring the inclusive SM top pair production asymmetry AFC at LHC 14 as a function of systematic error, and show that some improvement over current systematic uncertainties, as customarily handled, is required for observing a SM-size asymmetry.

This is the summary report of the Top Quark Kinematics working group prepared for Snowmass 2013. We survey the current state of theoretical predictions for top pair differential distributions, in both boosted and un-boosted regimes, and present an overview of uncertainties and prospects for top spin correlations. We study the prospects for measuring the inclusive SM top pair production asymmetry AFC at LHC 14 as a function of systematic error, and show that some improvement over current systematic uncertainties, as customarily handled, is required for observing a SM-size asymmetry. Cuts on top pair invariant mass and rapidity do not substantially alter this conclusion. We summarize the conclusions of contributed studies on alternate LHC measurements of the ttbar production asymmetry, in ttbar+jet final states and in forward top production at LHCb, both of which show good prospects for observing SM-size asymmetries in 50 fb-1 of data at LHC14.
