Atlas is investigating two techniques of in-situ jet calibration techniques. Both take advantage of the pT balance between a photon and a jet. I am investigating using the Missing ET projection fraction technique, which balances the well-measured photon against all other calorimetirc activity in the event. The main page describing this technique, along with links to talks and notes and recent results is here.
