One universal extra dimension in Pythia

Abstract The Universal Extra Dimensions model has been implemented in the Pythia generator from version 6.4.18 onwards, in its minimal formulation with one TeV^(-1)-sized extra dimension. The additional possibility of gravity-mediated decays, through a variable number of eV^(-1)-sized extra dimensions into which only gravity extends, is also available. The implementation covers the lowest lying Kaluza-Klein (KK) excitations of Standard Model particles, except for the excitations of the Higgs field... Title of program: PYTHIA Version number: 6.420 Catalogue Id: ACTU_v2_1 Nature of problem At high energy collisions between elementary particles, physics beyond the Standard Model is searched for. Many models are being investigated, namely extra dimensional models.
