The CMS Pixel Detector\\ for the High Luminosity LHC / Sguazzoni, Giacomo (INFN, Florence) /CMS Collaboration
The High Luminosity Large Hadron Collider (HL-LHC) at CERN is expected to collide protons at a centre-of-mass energy of 14 TeV and to reach the unprecedented peak instantaneous luminosity of $5-7.5\times10^{34} \,\mathrm{cm}^{-2}\mathrm{s}^{-1}$ with an average number of pile-up events of 140-200. This will allow the ATLAS and CMS experiments to each collect integrated luminosities up to $3000-4500\,\mathrm{fb}^{-1}$ during the project lifetime. [...]

Higgs Couplings in CMS in Run2 / Cooperstein, Stephane B (Princeton U.) /CMS Collaboration
The latest results on Higgs boson couplings using Run-2 data collected by the CMS experiment are presented. These recent developments include the confirmation of what had been the two remaining third generation Yukawa couplings yet to be observed, the top quark and bottom quark couplings. [...]

Search for Supersymmetry in final states with photons and missing transverse momentum in proton-proton collisions at 13 TeV / Paspalaki, Garyfallia (Democritos Nucl. Res. Ctr.) /CMS Collaboration
The results of a search for new physics in final states with photons and missing transverse momentum are reported. The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$ collected at a center-of-mass energy of 13 TeV using the CMS detector at the CERN LHC. [...]

Strong SUSY at ATLAS and CMS / Strobbe, Nadja Catharina (Fermilab) /ATLAS and CMS Collaborations
Supersymmetry (SUSY) remains one of the most elegant theories of new physics. The experiments at the LHC are able to put strong constraints on strongly produced SUSY particles. [...]

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. [...]

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.
