Description
Using 5.4 fb-1 of data from ppbar collisions at sqrt(s)=1.96 TeV recorded
with the D0 detector at the Fermilab Tevatron collider we investigate
various models of new physics using final states with new long-lived
particles. We investigate models in which charged massive long-lived
particles are pair produced, as well as models in which a single heavy
ionizing state is observed in the detector. Such state could arise as
the bound state of pairs of new fermions bound by a new SU(N) "infracolor"
gauge coupling (quirks). We also investigate models in which relatively
light particles exist in a "potential valley" separated from the standard
model by a high potential barrier. This barrier could be crossed leading to
the production of hidden valley particles which could decay to standard
model particles after moderately short lifetimes. Results from multiple
searches for hidden valley particles will be presented.
