Linear power corrections to single top production processes at the LHC

A bstract We discuss the linear power corrections to electroweak production of top quarks at LHC using renormalon calculus. show how such non-perturbative can be obtained Low-Burnett-Kroll theorem, which provides first subleading term expansion real-emission amplitudes around soft limit. demonstrate that there are no total cross sections arbitrary processes a single type provided these expressed in terms short-distance quark mass. also derive universal formula for generic observables involve top-quark momentum.
