  We discuss possibilities of detecting neutral and charged long-lived
particles with the upgraded D0 detector in Run II of the Fermilab Tevatron
accelerator, using photon pointing, dE/dx, and time-of-flight techniques. Such
particles appear in many SM extensions, e.g., Gauge Mediated SUSY. This work
has been done in the context of the BTMSSM Working group of the Run II
SUSY/Higgs Workshop at Fermilab.
