Hard QCD Measurements at LHC / Pasztor, Gabriella (Eotvos U.) /ATLAS, CMS and LHCB Collaborations
The rich proton-proton collision data of the LHC allow to study QCD processes in a previously unexplored region with ever improving precision. This paper summarises recent results of the ATLAS, CMS and LHCb Collaborations using primarily multi-jet and vector boson plus jet data collected at $\sqrt s$ = 8 and 13 TeV. [...]

The CBC3 readout ASIC for CMS 2S-modules / Uchida, Kirika (Imperial Coll., London) ; Auzinger, Georg (CERN) ; Bell, Stephen Jean-marc (Rutherford) ; Borg, Johan (Imperial Coll., London) ; Braga, Davide (Rutherford) ; Goldstein, Joel (Bristol U.) ; Hall, Geoffrey (Imperial Coll., London) ; Jones, Lawrence (Rutherford) ; Key-Charriere, M ; Murray, P et al.
The CBC3 is the latest version of the CMS Binary Chip for readout of the outer radial region of the upgraded CMS Tracker at the High Luminosity LHC. This 254-channel, 130 nm CMOS ASIC is designed to be bump-bonded to a substrate to which sensors will be wire-bonded. It will instrument double-layer 2S-modules, containing two overlaid silicon microstrip sensors, aligned with a parallel orientation. [...]

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 400 bps.

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.

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. [...]

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). [...]
