Description
In this talk the $\mathcal{O}(\Lambda_{QCD})$ corrections to processes with top-quarks will be discussed. A general method to compute these corrections based on renormalon calculus and the Low-Burnett-Kroll theorem will be discussed. We will show that linear power corrections vanish for the total cross-section. We also compute such corrections to top-quark kinematic distributions and show that they can be as large as a percent in certain kinematic regions.
