String Models
editThe subsection on String models, and the Bag model contains no mention of the subject of the article, the QCD vacuum. Deletion is recommended, and if someone wants to write a subsection perhaps on what AdS/CFT has to say on the subject that would be wonderful. Other sections are relevant, but for a non-expert, they do not explain what the relation between the concept discussed and QCD vacuum. Examples are PCAC and gradient coupling. Seems that exert help is neede to improve this key article of the QCD category.—Preceding unsigned comment added by 122.192.43.74 (talk) 16:53, 30 October 2009 (UTC)
