Abstract
Using the identification of jets originating from b quarks, we eliminate a source of background in our search for the dark photon. These “b-tagged” jets often contain lepton pairs that are similar to the decay of dark photons. A veto against these jets further isolates the dark photon signal, aiding in analysis. The extent to which efficiency changes due to the veto is compiled. Additionally, b- tagged jets in proximity to other leptons are exclusively filtered which makes vetoing considered in a fewer number of necessary cases. The framework is updated with an “Info Map” to support adding variables, such as the b-jet tag, that are utilized during analysis.
