Concats are separated by \&.
\| separates branches. See :h regex.

In general regex terms, | can be used thus:

(expression made an atom by the parentheses)|(and another one)

The whole regex will match if any of the branches do.

The low level of magic you're using obscures the underlying regex in an
unreadable backslash storm. (:h magic : \v cleans up all that crap, and
brings Vim very close to Posix regex conformity.)
Hopefully my general advice will put you on the right track, though.
