 FED Firmware Interface Testing with Pixel Phase 1 Emulator / Kilpatrick, Matthew (Rice U.) /CMS Collaboration A hardware emulation of the CMS pixel detector phase 1 upgrade front-end electronics has been developed to test and validate the architecture of the back-end electronics (FED) firmware. The emulation is implemented on a Virtex 6 FPGA on the CERN GLIB uTCA platform, utilizing an 8-way SFP FPGA Mezzanine Card to drive compatible optical transmitters to the back-end electronics at \mbox{400 Mbps}.

 Construction and beam-tests of silicon-tungsten and scintillator-SiPM modules for the CMS High Granularity Calorimeter for HL-LHC / Chang, Yung-wei (Taiwan, Natl. Central U.) /CMS Collaboration A High Granularity Calorimeter (HGCAL) is being designed to replace the existing endcap calorimeters in CMS for the HL-LHC era. It features unprecedented transverse and longitudinal segmentation for both electromagnetic (ECAL) and hadronic (HCAL) compartments, with silicon sensors being chosen for the high-pseudorapidity regions due to their radiation tolerance.

 Recent Heavy Flavour results from CMS / Lacaprara, Stefano (INFN, Padua) /CMS Collaboration Recent results on b-flavour physics obtained by the CMS Collaboration will be presented. The flexible and poweful CMS trigger system allows the experiment to be sensitive to b-physics phenomena of different kinds, mostly in channels with muons in the final state.

 Upgrades of the CMS muon system in preparation of HL-LHC / Teyssier, Daniel Francois (Aachen, Tech. Hochsch.) /CMS Collaboration The present CMS muon system operates three different detector types in the barrel drift tubes (DT) and resistive plate chambers (RPC), along with cathode strip chambers (CSC) and another set of RPCs in the forward regions. In order to cope with increasingly challenging conditions various upgrades are planned to the trigger and muon systems. [...] CMS-CR-2017-445.- Geneva : CERN, 2017 - 5 p.

 The CMS ECAL Upgrade for Precision Crystal Calorimetry at the HL-LHC / Petyt, David Anthony (Rutherford) /CMS Collaboration The electromagnetic calorimeter (ECAL) of the Compact Muon Solenoid Experiment (CMS) is operating at the Large Hadron Collider (LHC) in 2016 with proton-proton collisions at 13 TeV center-of-mass energy and at a bunch spacing of 25 ns. Challenging running conditions for CMS are expected after the High-Luminosity upgrade of the LHC (HL-LHC). [...] CMS-CR-2018-006.- Geneva : CERN, 2018 - 8 p.

 Systematic studies of charge-dependent azimuthal correlation in pPb and PbPb collisions at the LHC / Tu, Zhoudunming (Rice U.) /CMS Collaboration Studies of charge-dependent azimuthal correlations for same- and opposite-sign particle pairs are presented in PbPb collisions at 5.02 TeV and pPb collisions at 5.02 and 8.16 TeV, with the CMS experiment at the LHC. The azimuthal correlations are evaluated with respect to the second- and also higher-order event planes, as a function of particle pseudorapidity and transverse momentum, and event multiplicity.
