Search for diboson resonances in the semileptonic $\mathrm{X}\rightarrow\mathrm{Z}\mathrm{V}\rightarrow\ell^+\ell^-~\mathrm{q\bar{q}}$ final state at $\sqrt{s} = 13~\mathrm{TeV}$ with CMS /CMS Collaboration
A search for diboson resonances is performed in the semileptonic $\mathrm{X}\rightarrow\mathrm{Z}\mathrm{V}\rightarrow\ell^+\ell^-~\mathrm{q\bar{q}}$ final state, where one vector boson decays hadronically ($\mathrm{V} = \mathrm{W}, \mathrm{Z}$) and the other, a Z boson, decays into two leptons, in the mass range $550 \le m_\mathrm{ZV} \le 2500~\mathrm{GeV}$. In this regime the $\mathrm{V}$ boson may be sufficiently boosted that its decay products are contained in a single jet, thus merged jet reconstruction and substructure techniques are utilised. [...]

Search for single production of vector-like quarks decaying into final states with a Z boson and a top or a bottom quark /CMS Collaboration
A search for the single production of vector-like quarks, $T$ and $B$, decaying into a Z boson and a top or a bottom quark respectively, is presented using data collected by the CMS experiment in proton-proton collisions at $\sqrt s=13~\mathrm{TeV}$. An additional exotic production mode is studied for the $T$ quark, i.e. [...]

Performance of reconstruction and identification of tau leptons in their decays to hadrons and tau neutrino in LHC Run-2 /CMS Collaboration
The CMS hadrons-plus-strips (HPS) algorithm that was developed to reconstruct tau leptons in their hadronic decays demonstrated a good performance in the LHC Run-1; the algorithm achieves an identification efficiency of 50 -- 60\% with a probability for quark and gluon jets, electrons, and muons to be misidentified as $\tau$ lepton between per cent and per mille levels. In this paper improvements to the HPS algorithm for the LHC Run-2 are described. [...]

Identification of double-b quark jets in boosted event topologies /CMS Collaboration
Searches for new physics at the LHC necessitate to distinguish the merged decay products of resonances produced with high transverse momentum, from jets that originate from single partons. We present an algorithm that aims to reconstruct the $\mathrm{b\overline{b}}$ decay mode of such resonances. [...]
