Measurement of total and differential cross sections of central exclusive $\pi^+\pi^-$ production in proton-proton collisions at $5.02$ and $13~\mathrm{TeV}$ /CMS Collaboration
Central exclusive production of $\pi^+\pi^-$ pairs is investigated with the CMS detector in proton-proton collisions at the LHC at center-of-mass energies of $5.02$ and $13~\mathrm{TeV}$. The theoretical description of these non-perturbative processes, which are not sufficiently explored experimentally at the LHC, pose a significant challenge to models. [...]

CMS luminosity measurement for the 2018 data-taking period at $\sqrt{s} = 13~\mathrm{TeV}$ /CMS Collaboration
The calibration of the luminosity measurement by the CMS experiment in the 2018 proton-proton data taking at $\sqrt{s} = 13~\mathrm{TeV}$ is described. The principal calibration is derived from the analysis of the van der Meer scan program in CMS taken during LHC fill 6868. [...]

Search for top squark pair production in a di-tau final state in proton-proton collisions at $ \sqrt{s} = 13~\mathrm{TeV} $ /CMS Collaboration
A search for the pair production of the supersymmetric partner of the top quark, the top squark, produced in proton-proton collision events at $ \sqrt{s} = 13~\mathrm{TeV} $ is presented in final states containing hadronically decaying tau leptons and large missing transverse momentum. These final states are highly sensitive to high $ \tan{\beta} $ or higgsino-like scenarios in which decays of electroweak gauginos to tau leptons are dominant. [...]

Production of Lambda(c) in pp and PbPb collisions at sqrt(s) = 5.02 TeV /CMS Collaboration
The differential cross sections of $\Lambda_C^{+}$ baryon production are measured via the exclusive decay channel $\Lambda_C^{+}\to p K^{-}\pi^{+}$, as a function of transverse momentum ($p_T$) in proton-proton (pp) and lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02$~\mathrm{TeV}$ with the CMS detector at the LHC. The measurement is performed within the $\Lambda_C^{+}$ rapidity interval $|y| < 1.0$ in the $p_T$ range of 5-20 GeV/$c$ in pp and 10-20 GeV/$c$ in PbPb collisions. [...]

Search for supersymmetry using Higgs boson to diphoton decays at $\sqrt{s}$ = $13~\mathrm{TeV}$ with the CMS detector /CMS Collaboration
A search for supersymmetry is presented where at least one Higgs boson is produced and decays to two photons in the decay chains of the pair-produced supersymmetric particles. The presence of charged leptons and additional Higgs boson candidates and various kinematic variables are used to categorize events into search regions which are sensitive to different supersymmetry scenarios.

This note reports on a search for an extended scalar sector of the standard model, where a new CP-even (odd) scalar decays to a Z boson and a lighter CP-odd (even) scalar, which further decays to $\mathrm{b}\overline{\mathrm{b}}$. The Z boson is reconstructed via its decays to leptons. [...]

Measurement of the $\mathrm{t}\overline{\mathrm{t}}\mathrm{b}\overline{\mathrm{b}}$ production cross section in the all-jet final state in $\mathrm{pp}$ collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A measurement of the production cross section of top quark pairs in association with two b jets ($\mathrm{t}\overline{\mathrm{t}}\mathrm{b}\overline{\mathrm{b}}$) is presented, using data collected in $\mathrm{pp}$ collisions at $\sqrt{s}=13~\mathrm{TeV}$ by the CMS experiment at the LHC corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. The cross section is measured in the all-jet decay channel of the top quark pairs by selecting events containing at least eight jets, of which two are identified as originating from the hadronisation of b quarks.

A measurement of the associated production of a standard model Higgs boson with a top quark-antiquark pair ($\mathrm{t\overline{t}H}$) in proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$ is presented. The result is based on data recorded with the CMS detector at the CERN LHC in 2017 and corresponds to an integrated luminosity of $41.5\,\mathrm{fb}^{-1}$ [...]
