Sometimes it make you just want to find another article! :-)
The punctuation isn't the real issue, it's just a convenient guideline. The real question is whether the second part is part of the title, or is a separate subtitle. Technically, a subtitle is a "secondary portion of the title proper of a work, usually consisting of an explanatory or limiting phrase, following a colon or semicolon and often beginning with ''" or 'an'." http://www.abc-clio.com/ODLIS/searchODLIS.aspx .
That isn't what you have here. The second part of the title is more of a title than the first part. The first part is technically a catchword title. For your purposes, it means that you treat the whole thing as the title, and capitalize only the first word, "The". There is no need to capitalize "background".
