    Symbol over a line

    Say that I want to put a W stacked on top of a line, say \overline. For example, I want to specify that an interaction
    is mediated by a Z particle. I want to put a small Z over the arrow.

    Re: Symbol over a line

    I think you use overset:

    For example,
    Code:
    \overset{z}{\rightarrow}
    displays as follows

    \overset{z}{\rightarrow}

    e^- + e^- \overset{Z^0}{\longrightarrow} e^- + e^-

    That's the one! Thanks.
