One universal extra dimension in Pythia
Description
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.
