How best to add LaTeX expressions in Illustrator

Dear all,

I am working on a musical score which needs to have graphics and text added to it for analytical purposes. Most of the text is made up of LaTeX equations and I was wondering what my best options were.

Currently (and possibly for a very long time), the notational softwares I use will not support LaTeX (simply because it would be used by 1‰ of the userbase to be optimistic), so I am writing the equation in Apple Pages, exporting them as PDF and then pasting them in Illustrator as graphics above the music PDF which composes the artboards. 

Is this the best way? Are there fonts that support superscript/subscript + overset combinations otherwise that would work better? 

Here is an example of what I need to use: 

Thank you
