摘要：

The associated tW single top production channel is one of the main mechanism of the electroweak production of top quarks at the LAIC. Correct simulation of the SM prediction for this process is one of the important tasks in the SM measurements and BSM searches. One of the difficulties to simulate it correctly is a significant contribution of the interference terms with the pair top quark production. In this article authors compare most popular simulation schemes for tW production with simulation of the complete set of diagrams and propose new scheme to simulate interference terms without negative weights of the events.
