Studien des Top-Antitop-Untergrundes in SUSY-Suchen durch vollständige Rekonstruktion bei CMS

This work studies the complete kinematic reconstruction of top quark pairs through their decay products under the constraint that one top-quark decays semileptonically into one myon and the other top-quark decays hadronically. Monte-Carlo data are used so one has access to the generator information....

Sumario:This work studies the complete kinematic reconstruction of top quark pairs through their decay products under the constraint that one top-quark decays semileptonically into one myon and the other top-quark decays hadronically. Monte-Carlo data are used so one has access to the generator information. The developed algorithm is then applied to the SUSY models LM0 and LM1, and it is shown how possible supersymmetric particles can be separated from the top background.
