Rare Z and H decays to quarkonia / Torres Da Silva De Araujo, Felipe (Rio de Janeiro State U.) /CMS Collaboration
Rare decay modes of the Z and Higgs bosons involving the production of quarkonium states offer a very clean experimental signature. A search for the Z and H decays to final states with a $J/\psi$ meson and a photon, and the rare Z decay to a lepton pair and a vector meson is performed using data collected by the CMS experiment.

Status of the CMS experiment, highlights and perspectives / Butler, Joel Nathan (Fermilab) /CMS Collaboration
The Large Hadron Collider began providing proton-proton collisions at 13 TeV center-of-mass energy in 2015 and has achieved very high luminosity and reliability. By the fall of 2018, it has delivered more than 120 fb$^{-1}$ to the CMS Experiment, with more than 150 fb$^{-1}$ expected before a two-year shutdown for accelerator and detector upgrades starting in December of 2018.

art@CMS SciArt Workshops / Hoch, Michael (Vienna, OAW) /CMS Collaboration
Recent developments in science education policy and practice suggest that successful learning in the 21st century requires the horizontal connectedness across areas of knowledge by linking the arts and humanities with science, technology, engineering and mathematics (STEM) subjects. The rapidly increasing STEAM movement calls for arts integration into science teaching and learning to help school students develop skills that are necessary to thrive in an innovation economy. [...]

Measurements of bottomonium production in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}\space}$ = 5.02 TeV / Oh, Geonhee (Chonnam Natl. U.) /CMS Collaboration
Bottomonia are important probes of the quark-gluon plasma since they are produced at early times and propagate through the medium. The production cross sections of the three $\Upsilon$ states (1S, 2S, 3S) were measured by CMS in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}\space}$ = 5.02 ${\mathrm{TeV}}\space$. [...]

Supersymmetry searches at CMS / Kazana, Malgorzata (NCBJ, Warsaw) /CMS Collaboration
The CMS experiment at the LHC has published results derived from a dataset of an integrated luminosity $\mathcal{L}$=$35.9$fb$^{-1}$ recorded with proton-proton collisions at centre-of-mass energy $\sqrt{s}=13$ TeV in 2016. In this overview, the selected CMS results of searches for supersymmetry are presented as available in the summer of 2018..

Constraints on nuclear parton distribution functions with dijets in pp, pPb collisions at $\sqrt s$~=~5.02~TeV with the CMS detector / Go, Yeonju (Korea U.) /CMS Collaboration
Dijet measurements in pPb collisions have been shown to be one of the most important tools for constraining the gluon nuclear parton distribution functions (nPDFs) at large Bjorken x. The dijet pseudorapidity distributions are measured as a function of dijet average transverse momentum in order to study the nuclear modifications of PDFs at various factorization scales. [...]

The CMS Tracker Upgrade for the High Luminosity LHC / Sguazzoni, Giacomo (INFN, Florence)
The LHC machine is planning an upgrade program which will smoothly bring the luminosity to about $5-7.5\times10^{34}$cm$^{-2}$s$^{-1}$ in 2028, to possibly reach an integrated luminosity of $3000-4500\;$fb$^{-1}$ by the end of 2039. This High Luminosity LHC scenario, HL-LHC, will require an upgrade program of the LHC detectors known as Phase-2 upgrade. [...]
