Abstract
The purpose of this work is the development of a new analysis technique that allows the determination of differential cross sections with respect to arbitrary kinematic variables. This is illustrated for top quark pairs production where two leptons are present in the final state together with two neutrinos that cannot be detected. By estimating the t¯t invariant mass and the angle between the top quarks in the t¯t rest frame, the sensitivity to the presence of new physics is demonstrated. This technique, based on the matrix element method, makes the optimal use of the experimental information given a set of theoretical hypotheses.
