Performance of Deep Tagging Algorithms for Boosted Double Quark Jet Topology in Proton-Proton Collisions at 13 TeV with the Phase-0 CMS Detector

For many searches for new physics at the LHC, it is important to distinguish jets that originate from the merged decay products of resonances produced with high transverse momentum from jets that originate from single partons. We present three algorithms that aim to distinguish the b$\mathrm{\bar{b}}$ and c$\mathrm{\bar{c}}$ decay modes of such resonances from light flavour jets, as well as distinguish between the two. The algorithms are applicable to any resonance with the mass close to 100 GeV and with high enough energy for its decay products to be clustered in a single jet within a cone of size R=0.8. An example is the 125 GeV Higgs boson which is the focus of this Detector Performance Summary. Expected performance of the three algorithms in simulation with the Phase-0 CMS tracker detector are presented.
