Missing ET Symbol

Hi,
So this is off-topic for me. Is it possible to draw the missing E_T symbol in a ROOT plot caption (The E_{T} with a slash through it)?

Many thanks!
Cheers,
Gordon.

Look at the doc: root.cern.ch/root/html/TLatex.html
It is explain there.
To make it short: #slash{E}_{T}

Thanks!
