Contribution
It provides a global fit of top quark BSM couplings via effective operators, integrating data from LHC and Tevatron, and discusses future prospects.
Findings
Combined LHC and Tevatron data constrain top BSM couplings.
Differential measurements enhance sensitivity to new physics.
Projections indicate significant improvements with LHC Run II.
Abstract
We discuss a global fit of top quark BSM couplings, phrased in the model-independent language of higher-dimensional effective operators, to the currently available data from the LHC and Tevatron. We examine the interplay between inclusive and differential measurements, and the complementarity of LHC and Tevatron results. We conclude with a discussion of projections for improvement over LHC Run II.
