Top quark pair production and decay at linear colliders: signal vs. off resonance background

Abstract

Standard Model predictions for the reactions with six fermions in the final state relevant for top quark pair production and decay at linear colliders are discussed. An issue of the double resonance signal versus non doubly resonant background is addresed. Effects related to the off-mass-shell production of the t\bar{t}-pair are discussed.Comment: 9 pages, talk presented by K.
