Measurement of high $p_T$ isolated prompt photons in lead-lead collisions at $\sqrt{s_NN}$=2.76 TeV with the ATLAS detector at the LHC
Prompt photons are a powerful tool to study heavy ion collisions. Their production rates provide access to the initial state parton distribution functions and also provide a means to calibrate the expected energy of jets that are produced in the medium. The ATLAS detector measures photons with its h...
