Measurement of associated Z + charm production in proton-proton collisions at $\sqrt{s} = $ 8 TeV
[CMS-SMP-15-009; CERN-EP-2017-257; arXiv:1711.02143]
A study of the associated production of a $\mathrm{Z} $ boson and a charm quark jet ( $\mathrm{Z} + \mathrm{c} $ ), and a comparison to production with a $\mathrm{b} $ quark jet ( $\mathrm{Z} + \mathrm{b} $ ), in $\mathrm {p}\mathrm {p}$ collisions at a centre-of-mass energy of 8 $\,\text {TeV}$ are presented. The analysis uses a data sample corresponding to an integrated luminosity of 19.7 $\,\text {fb}^{-1}$ , collected with the CMS detector at the CERN LHC. [...]

Measurement of the inclusive $ \mathrm{t}\overline{\mathrm{t}} $ cross section in pp collisions at $ \sqrt{s}=5.02 $ TeV using final states with at least one charged lepton
[TOP-16-023; CERN-EP-2017-258; arXiv:1711.03143]
The top quark pair production cross section $ \left({\sigma}_{\mathrm{t}\overline{\mathrm{t}}}\right) $ is measured for the first time in pp collisions at a center-of-mass energy of 5.02 TeV. The data were collected by the CMS experiment at the LHC and correspond to an integrated luminosity of 27.4 pb$^{−1}$. [...]

Search for ZZ resonances in the 2$\ell$2$\nu$ final state in proton-proton collisions at 13 TeV
[CMS-B2G-16-023; CERN-EP-2017-279; arXiv:1711.04370]
A search for heavy resonances decaying to a pair of Z bosons is performed using data collected with the CMS detector at the LHC. Events are selected by requiring two oppositely charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum, which is interpreted as arising from the decay of a second Z boson to two neutrinos.

Search for excited states of light and heavy flavor quarks in the $\gamma$+jet final state in proton-proton collisions at $\sqrt{s} =$ 13 TeV
[CMS-EXO-17-002; CERN-EP-2017-271; arXiv:1711.04652]
A search is presented for excited quarks of light and heavy flavor that decay to $\gamma$+jet final states. The analysis is based on data corresponding to an integrated luminosity of 35.9 fb$^{-1}$ collected by the CMS experiment in proton-proton collisions at $\sqrt{s}=$ 13 TeV at the LHC. [...]

Search for gauge-mediated supersymmetry in events with at least one photon and missing transverse momentum in pp collisions at $\sqrt{s} = $ 13 TeV
[CMS-SUS-16-046; CERN-EP-2017-284; arXiv:1711.08008]
A search for gauge-mediated supersymmetry (SUSY) in final states with photons and large missing transverse momentum is presented. The data sample of pp collisions at s=13TeV was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 35.9 fb −1 . [...]

Search for new long-lived particles at $\sqrt{s} =$ 13 TeV
[CMS-EXO-16-003; CERN-EP-2017-264; arXiv:1711.09120]
A search for long-lived particles was performed with data corresponding to an integrated luminosity of 2.6 fb −1 collected at a center-of-mass energy of 13 TeV by the CMS experiment in 2015. The analysis exploits two customized topological trigger algorithms, and uses the multiplicity of displaced jets to search for the presence of a signal decay occurring at distances between 1 and 1000 mm.

Measurements of the $\mathrm {p}\mathrm {p}\rightarrow \mathrm{Z}\mathrm{Z}$ production cross section and the $\mathrm{Z}\rightarrow 4\ell $ branching fraction, and constraints on anomalous triple gauge couplings at $\sqrt{s} = 13\,\text {TeV} $
[CMS-SMP-16-017; CERN-EP-2017-219; arXiv:1709.08601]
Four-lepton production in proton-proton collisions, $\mathrm {p}\mathrm {p}\rightarrow (\mathrm{Z}/ \gamma ^*)(\mathrm{Z}/\gamma ^*) \rightarrow 4\ell $ , where $\ell = \mathrm {e}$ or $\mu $ , is studied at a center-of-mass energy of 13 $\,\text {TeV}$ with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 $\,\text {fb}^{-1}$ . [...]

Search for new phenomena in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum in pp collisions at $ \sqrt{s}=13 $ TeV
[CMS-SUS-16-034; CERN-EP-2017-170; arXiv:1709.08908]
Search results are presented for physics beyond the standard model in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 35.9 fb$^{−1}$ of proton-proton collisions at $ \sqrt{s}=13 $ TeV collected with the CMS detector at the LHC in 2016. [...]

Search for supersymmetry in events with one lepton and multiple jets exploiting the angular correlation between the lepton and the missing transverse momentum in proton-proton collisions at $\sqrt{s} = $ 13 TeV

Results are presented from a search for supersymmetry in events with a single electron or muon and hadronic jets. The data correspond to a sample of proton–proton collisions at s=13TeV with an integrated luminosity of 35.9 fb−1 , recorded in 2016 by the CMS experiment. [...]

Study of dijet events with a large rapidity gap between the two leading jets in pp collisions at $\sqrt{s}=7$ $\,\text {TeV}$
[CMS-FSQ-12-001; CERN-EP-2017-141; arXiv:1710.02586]
Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at $\sqrt{s}=7$ $\,\text {TeV}$ . The jets were required to have transverse momentum $p_{\mathrm {T}} ^{\text {jet}}>40$ $\,\text {GeV}$ and pseudorapidity $1.5<|\eta ^{\text {jet}} |<4.7$ , and to have values of $\eta ^{\text {jet}}$ with opposite signs.
