Identification of Parton Pairs in a Dijet Event and Investigation of Its Effects on Dijet Resonance Search

Figure 4

(a) Improvement of signal significance ratio as a function of resonance mass after applying parton tagging. The tagging discriminator is chosen at 80% signal efficiency. (b) Improvement of signal significance as a function of signal efficiency cut at the resonance mass of 5 TeV. In both plots, black dashed line shows gluon-gluon resonances, red dashed line present quark-gluon resonances, and purple dashed line shows quark-quark resonances.
