Pentaquark Searches in Electron-Positron Annihilations and Two-Photon Collisions at LEP

Evidence for the production of exotic hadron states composed of five quarks (pentaquarks) has been searched for in data collected by the ALEPH, DELPHI, and L3 experiments at LEP. No significant signal is observed. Several 95% C.L. upper limits are set on the production rates of such particles.

New Results on Bs Mixing from LEP

The phenomenology of B_s^0 oscillations is reviewed along with the experimental strategy for observing them. Results of studies from ALEPH, DELPHI, and OPAL experiments are summarized with an emphasis on recent new results from ALEPH.
