Space between a|b in math mode?

For a context free grammar I need to write:

A -> a | b

My code for this is

$ A \rightarrow a | b $

however this gives me something like

A -> a|b // wanted: a | b, note the space before and after the |

meaning there is no space between a|b.

How can I fix this?

Thanks for any hint!

Use \mid that will produce the same spacing as \rightarrow – egreg Mar 07 '13 at 16:00
