General title curation
The title of a paper or book in HEP goes in 245__a. As a general rule, only the first letter of the first word of the title is capitalized, along with any proper names or acronyms. If hyphens are used in the title, only use a single hyphen rather than a double one.
The published version of the paper has the official title. Any other versions go in 246__a, including arXiv titles (with 246__9:arXiv to indicate the source).
Titles should include LaTeX to properly display math symbols and Greek letters. Instructions on using LaTeX are here.
