Search for new particles decaying to a jet and an emerging jet /CMS Collaboration
A search for events consistent with the pair production of a heavy mediator particle that decays to a light quark and a new fermion, called a dark quark, is performed using data corresponding to an integrated luminosity of $16.1~\mathrm{fb}^{-1}$ from proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ collected by the CMS experiment at the LHC in 2016. The dark quark is charged only under a new quantum chromodynamic-like force, and forms long-lived dark hadrons via a parton shower. [...]

Observation of the $\mathrm{B}^{*}_{\mathrm{s}2}(5840)^0\rightarrow\mathrm{B}^0\mathrm{K}^0_{\mathrm\scriptscriptstyle S}$ decay and studies of excited $\mathrm{B}^0_\mathrm{s}$ mesons in proton-proton collisions at $\sqrt{s}=8\,\mathrm{TeV}$ /CMS Collaboration
The observation of the $\mathrm{B}^{*}_{\mathrm{s}2}(5840)^0\rightarrow\mathrm{B}^0\mathrm{K}^0_{\mathrm\scriptscriptstyle S}$ decay is presented and a measurement of its relative branching fraction to the $\mathrm{B}^{*}_{\mathrm{s}2}(5840)^0\rightarrow\mathrm{B}^+\mathrm{K}^{-}$ decay using a data sample of $19.6\,\mathrm{fb}^{-1}$ collected with the CMS detector in proton-proton collision at the centre-of-mass energy $8\,\mathrm{TeV}$. The analysis is performed by studying P-wave $\mathrm{B}^{0}_\mathrm{s}$ meson decays into $\mathrm{B}^+\mathrm{K}^-$ and $\mathrm{B}^0 \mathrm{K}^0_{\mathrm\scriptscriptstyle S}$ states, where the ground-state $\mathrm{B}$ mesons are identified using the decays $\mathrm{B}^+ \rightarrow \mathrm{J}/\psi\mathrm{K}^+$ and $\mathrm{B}^0 \rightarrow \mathrm{J}/\psi\mathrm{K}^+ \pi^-$.

Search for resonant production of second generation sleptons with same-sign dimuon events in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A search for resonant production of second generation sleptons ($\tilde{\mu}$, $\tilde{\nu}_{\mu}$) via the R-parity-violating coupling $\lambda'_{211}$, in events with two same-sign muons and at least two jets in the final state is presented. While one muon is expected to be produced directly in the slepton decay, the second muon and at least two jets are produced in the subsequent decay of a neutralino or chargino originating from the resonant slepton.

Search for narrow H-gamma resonances in proton-proton collisions at sqrt(s) = 13 TeV /CMS Collaboration
A search for heavy, narrow-width resonances decaying to a Higgs boson and a photon has been performed in proton-proton collision data corresponding to an integrated luminosity of 35.9 inverse femtobarns, collected with the CMS detector at the LHC at a center-of-mass energy of 13 TeV in 2016. Events in which a photon and a Lorentz-boosted Higgs boson that decays hadronically and reconstructed as a single, large-radius jet are considered, and the photon+jet invariant mass spectrum is analyzed to look for the presence of narrow-width resonances.
