Whether to use direct photon or converted photon?

Find the potential background processes

Check if MC available for signal and background

• If not available then request the MC

Decide which analysis framework will be suitable

• Bmm4 as it is based on AOD
• If Bmm4, then talk to Chandi and understand the framework
• Port the framework for our use

Produce the ntuples for signal and background

Train the BDT for various invariant mass ranges

In parallel, Ruchi should study the photon fake rate from pi zero and QCD jets at low pT
