摘要: We calculate the one-loop non-factorizable QCD corrections to production and decay of pairs top quarks at various collider experiments. These interconnect different stages off-shell top-pair processes. This in particular affects invariant-mass distributions quarks, resulting a shift maximum distorted Breit-Wigner distributions. Although can be large, actual mass as determined from peak position corrected line-shape is below $100\MeV$.
