Does the new version supersede the previous version?: Yes
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.
The Universal Extra Dimension model is implemented in the PYTHIA event generator.
Reasons for new version:
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 StandardModel particles, except for the excitations of the Higgs fields, with the mass spectrum calculated at one loop. 2 -> 2 tree-level production cross sections and unpolarized KK number conserving 2-body decays are included. Mixing between iso-doublet and -singlet KK excitations is neglected thus far, and is expected to be negligible for all but the top sector.
10-1000 events per second, depending on the process studied.
