Can spontaneously broken gauge theories be asym free?

[metroplex021]

Hi folks -- it is my understanding that only non-Abelian gauge theories can be asymptotically free. But can anyone provide me with a canonical reference showing that such symmetries can be dynamically broken and still retain that status? I gather that this is the case (from reading the original papers by Gross and Wilczek, etc), but haven't managed to find anything where this is explicitly shown.

Any help would be much appreciated!
