Physics Topologies: Diphotons

Object ID Tasks

• assess existing j → γ estimation tools; apply them to jj and γ j MC and make closure tests. Same for W/Z+jet.
• Assess existing e → γ estimation tools; identify improvements
• Assess existing j → l estimation tools; apply them to γ bbar MC, make closure tests.
• Develop common ways to deal with cosmic/halo background; it obviously matters more for channels with missing ET, but can be important even for γ+jet at high ET
• Assess existing ways of identifying off-pointing and/or delayed photons for searched of long-lives massive particles
