A new way of reducing negative weights in MC@NLO
Author
Summary, in English
We introduce a new technique, that we dub Born spreading, aimed at reducing the number of negative-weight S events in the MC@NLO matching of NLO calculations with parton-shower simulations. We show that such a technique, based on a re-distribution of Born matrix elements in the radiative phase space, achieves a sizeable reduction of negative-weight events at little computational cost. The method does not induce any biases in physical distributions.
