More information: OPAL public page for physicists and searching OPAL publications by topic
Two kinds of OPAL documents are referenced here:
1) Final OPAL publications are identified by PRxxx. They may be quoted without reservation. All published OPAL results
2) Preliminary OPAL results, in Physics Notes identified by PNxxx, may change before final publication. All preliminary OPAL results
Results identified by EBxxx refer to upcoming papers still under internal review.
