 AlphaTwirl: A Python library for summarizing event data into multivariate categorical data / Sakuma, Tai (Bristol U.) AlphaTwirl is a Python library that summarizes large event data into multivariate categorical data, which can be regarded as generalizations of histograms. The output can be imported as data frames in R and pandas. [...] CMS-CR-2018-405.- Geneva : CERN, 2018 - 9 p.

 Operational Experience of the Phase-1 CMS Pixel Detector / Vormwald, Benedikt Roland (Hamburg U.) /CMS Collaboration In 2017, CMS has installed a new pixel detector with 124 million channels that features full 4-hit coverage in the tracking volume and is capable of withstanding instantaneous luminosities of $2\times10^{34}\,\mathrm{cm}^{-2}\mathrm{s}^{-1}$ and beyond. Many of the key technologies of modern particle detectors are applied in this detector, like efficient DC-DC low-voltage powering, high-bandwidth $\mathrm{\mu}$TCA back-end electronics, and light-weight CO$_2$ cooling.

 The CMS Outer Tracker for the High-Luminosity LHC / Butz, Erik Manuel (KIT, Karlsruhe, EKP) The era of High-Luminosity Large Hadron Collider will pose unprecedented challenges for detector design and operation. The planned luminosity of the upgraded machine is $5$--$7.5\times{}10^{34} \,\mathrm{cm}^{-2}\mathrm{s}^{-1}$, reaching an integrated luminosity of 3000--4000\,fb$^{-1}$ by the end of 2039.

 Review of recent forward physics results from the CMS experiment / Ulrich, Ralf (KIT, Karlsruhe, IKP) /CMS Collaboration There is a rich program of forward physics measurements within the CMS Collaboration covering a wide range of topics. In many cases there is a connection to quantities and effects relevant for very high energy cosmic ray interaction.

 Serial Powering for Inner Tracker Detectors at the HL-LHC / Koukola, Dominik (CERN) ; Orfanelli, Stella (CERN) The Large Hadron Collider will be upgraded to deliver peak instantaneous luminosities up to 7.5x10$^{34}$ cm$^{-2}$s$^{-1}$ and up to 4000\,fb$^{-1}$ during the 10-year High Luminosity phase (HL-LHC). New silicon tracking detector systems will be installed to fully exploit the physics potential of the upgraded machine. [...] CMS-CR-2018-419.- Geneva : CERN, 2018 - 5 p.

 CMS emittance scans for luminosity calibration in 2017 / Karacheban, Olena (CERN) /CMS Collaboration Emittance scans are short van der Meer type scans performed at the beginning and at the end of LHC fills. The beams are scanned against each other in X and Y planes in 7 displacement steps. [...] CMS-CR-2018-063.- Geneva : CERN, 2018 - 6 p.

 Support for participating in outreach and the benefits of doing so / Rao, Achintya Mahesh (West England U.) This paper presents the preliminary analysis of data collected as part of a research project into the attitudes within the particle-physics community towards outreach in particular (known academically as public engagement) and science communication in general. The Compact Muon Solenoid (CMS) Collaboration at CERN's Large Hadron Collider was chosen as the sample to represent the population of particle-physics researchers (which includes engineers and students working in particle physics).

 Calibration and performance of the CMS electromagnetic calorimeter during the LHC Run II / Dimova, Tatyana (Novosibirsk State U.) /CMS Collaboration Many physics analyses using the Compact Muon Solenoid (CMS) detector at the LHC require accurate, high resolution electron and photon energy measurements. Excellent energy resolution is crucial for studies of Higgs boson decays with electromagnetic particles in the final state, as well as searches for very high mass resonances decaying to energetic photons or electrons.

 The performance of the CMS Muon system with data at $\sqrt s$ = 13 TeV / Hadjiiska, Roumyana Mileva (Sofiya, Inst. Nucl. Res.) /CMS Collaboration The muon spectrometer of the CMS experiment is based on three different gaseous detector technologies: Drift Tube (DT) chambers in the barrel, Cathode Strip Chambers (CSC) in the endcaps, and Resistive Plate Chambers (RPC) both in the barrel and endcaps. The performance of the muon system has been studied with LHC proton-proton collision data, collected with the CMS detector, at $\sqrt s$ = 13 TeV. [...] CMS-CR-2018-167.- Geneva : CERN, 2018 - 12 p.

 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.
