If you hold a CERN-TH contract or you are a registered visitor to CERN-TH for a period of at least two months, you can use the CERN-TH affiliation for articles describing research carried out entirely, or to a large extent, at CERN:
Theoretical Physics Department, CERN, 1211 Geneva 23, Switzerland
Any article authored by Staff, Fellows, Emeriti or Scientific Associates in TH should have a CERN-TH preprint number. It can be obtained using the following application form (in case of problems contact the TH preprint admin ). You should ask for a preprint number only when your article is close to completion. Do not forget to include your generated CERN-TH preprint number on the first page of your paper.
TH Staff members will always be happy to discuss the content or presentation of a paper, but their formal approval is not required. TH preprints are required to be written in good English (British spelling).
The Theoretical Physics Department has no budget to cover publication or reprint charges, however CERN does have an agreement with most journals that CERN articles are published as open access.
