Next-to-leading-order Weights for Jet Events in Hadron Collisions — •Till Martini — Humboldt Universität zu Berlin, PEP

In leading order there is a direct correspondence between jets and partons: each jet is modeled by a single parton. An improved theoretical prescription can be obtained using higher order predictions. Additional parton emission occuring in higher order corrections leads to an improved modeling of jets. In particular the recombination of two partons to one jet is allowed. Attributing next-to-leading-order weights to these configurations is highly non-trivial since it is not obvious how to uniquely identify the (n+1)-parton phase space contributing to a certain n-Jet phase space point. I demonstrate how this may be achieved and I discuss possible applications of NLO event weights.
