Search for pair production of vector-like quarks in the fully hadronic final state
[arXiv:1906.11903; CMS-B2G-18-005; CERN-EP-2019-129]
 GO
The results of two searches for pair production of vector-like T or B quarks in fully hadronic final states are presented, using data from the CMS experiment at a center-of-mass energy of 13 TeV. The data were collected at the LHC during 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. [...]

Combined search for supersymmetry with photons in proton-proton collisions at $\sqrt{s}=$ 13 TeV
[arXiv:1907.00857; CMS-SUS-18-005; CERN-EP-2019-114]
 GO
A combination of four searches for new physics involving signatures with at least one photon and large missing transverse momentum, motivated by generalized models of gauge-mediated supersymmetry (SUSY) breaking, is presented. All searches make use of proton-proton collision data at $\sqrt{s}=$ 13 TeV, which were recorded with the CMS detector at the LHC in 2016, and correspond to an integrated luminosity of 35.9 fb$^{-1}$.

Measurement of the top quark Yukawa coupling from $\mathrm{t\bar{t}}$ kinematic distributions in the lepton+jets final state in proton-proton collisions at $\sqrt{s} =$ 13 TeV
[arXiv:1907.01590; CMS-TOP-17-004; CERN-EP-2019-119]
 GO
Results are presented for an extraction of the top quark Yukawa coupling from top quark-antiquark ($\mathrm{t\bar{t}}$) kinematic distributions in the lepton plus jets final state in proton-proton collisions, based on data collected by the CMS experiment at the LHC at $\sqrt{s} =$ 13 TeV, corresponding to an integrated luminosity of 35.8 fb$^{-1}$. Corrections from weak boson exchange, including Higgs bosons, between the top quarks can produce large distortions of differential distributions near the energy threshold of $\mathrm{t\bar{t}}$ production.

Search for MSSM Higgs bosons decaying to $\mu^+\mu^-$ in proton-proton collisions at $\sqrt{s}=$ 13 TeV
[arXiv:1907.03152; CMS-HIG-18-010; CERN-EP-2019-109]
 GO
A search is performed for neutral non-standard-model Higgs bosons decaying to two muons in the context of the minimal supersymmetric standard model (MSSM). Proton-proton collision data recorded by the CMS experiment at the CERN Large Hadron Collider at a center-of-mass energy of 13 TeV were used, corresponding to an integrated luminosity of 35.9 fb$^{-1}$.

Measurement of the top quark polarization and $\mathrm{t\bar{t}}$ spin correlations using dilepton final states in proton-proton collisions at $\sqrt{s}=$ 13 TeV
[arXiv:1907.03729; CMS-TOP-18-006; CERN-EP-2019-073]
 GO
Measurement of the top quark polarization and $\mathrm{t\bar{t}}$ spin correlations are presented using events containing two oppositely charged leptons $(e^+ e^−, e^± μ^∓$, or $μ^+ μ^−)$ produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.9 fb$ ^{−1}$ [...]

Study of the B$^+ \to $J$/\psi\overline{\Lambda}$p decay in proton-proton collisions at $\sqrt{s}=$ 8 TeV
[arXiv:1907.05461; CMS-BPH-18-005; CERN-EP-2019-128]
 GO
A study of the B$^+\to $J$/\psi\overline{\Lambda}$p decay using proton-proton collision data collected at $\sqrt{s}=$ 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb$^{-1}$, is presented. The ratio of branching fractions $\mathcal{B}$(B$^+ \to $J$/\psi\overline{\Lambda}$p )$/\mathcal{B}$(B$^\to $J$/\psi$K$^*$(892)$^+$) is measured to be (1.054 $\pm$ 0.057 (stat) $\pm$ 0.035 (syst) $\pm$ 0.011 ($\mathcal{B}$))%, where the last uncertainty reflects the uncertainties in the world-average branching fractions of $\overline{\Lambda}$ and K$^*$(892)$^+$ decays to reconstructed final states.

Search for physics beyond the standard model in events with overlapping photons and jets
[arXiv:1907.06275; CMS-B2G-18-007; CERN-EP-2019-135]
 GO
Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. [...]

Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV
[arXiv:1907.08155; CMS-SMP-16-016; CERN-EP-2019-127]
 GO
Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV as a function of photon transverse momentum $(p_{T}^{\gamma})$, photon pseudorapidity $(η^{γ})$, and jet pseudorapidity $(η^{jet})$. The data correspond to an integrated luminosity of 19.7 fb$^{−1}$ that probe a broad range of the available phase space, for $|η^{γ}| <$ 1.44 and 1.57 $< |η^{γ}| <$ 2.50, $|η^{jet}| <$ 2.5, 40 $<p^{γ}_T <$ 1000 GeV, and jet transverse momentum, $p^{jet}_{T}, >$ 25 GeV [...]

Measurement of differential cross sections and charge ratios for $t$-channel single top quark production in proton-proton collisions at $\sqrt{s}=$ 13 TeV
[arXiv:1907.08330; CMS-TOP-17-023; CERN-EP-2019-138]
 GO
A measurement is presented of differential cross sections for $t$-channel single top quark and antiquark production in proton-proton collisions at a centre-of-mass energy of 13 TeV by the CMS experiment at the LHC. From a data set corresponding to an integrated luminosity of 35.9 fb$^{-1}$, events containing one muon or electron and two or three jets are analysed. [...]

Search for anomalous triple gauge couplings in WW and WZ production in lepton + jet events in proton-proton collisions at $\sqrt{s} =$ 13 TeV
[arXiv:1907.08354; CMS-SMP-18-008; CERN-EP-2019-137]
 GO
A search is presented for three additional operators that would lead to anomalousWW$γ$ or WWZ couplings with respect to those in the standard model. They are constrained by studying events with two vector bosons; a W boson decaying to e$ν$ or $μν$, and a W or Z boson decaying hadronically, reconstructed as a single, massive, large-radius jet [...]
