 Measurement and simulation of the background in the CMS muon detectors / Kang, Yechan (Seoul U.) /CMS Collaboration The CMS muon system presently consists of three detector technologies equipping different regions of the spectrometer. Drift Tube chambers (DT) are installed in the central region, while Cathode Strip Chambers (CSC) cover the high pseudorapidity regions; both serve as tracking and triggering detectors.

 Searches with boosted objects in ATLAS and CMS / Zucchetta, Alberto (Zurich U.) /ATLAS and CMS Collaborations A summary of searches for heavy resonances decaying into boosted bosons or top quarks is presented. The searches are performed on the data collected during 2016 and 2017 by the ATLAS and CMS experiments from pp collisions produced at the CERN LHC at $\sqrt{s}=13$ TeV.

 The CMS Level-1 muon triggers for the LHC Run II / Konecki, Marcin Andrzej (Warsaw U.) /CMS Collaboration The CMS experiment implements a sophisticated two-level triggering system composed of Level-1, instrumented by custom-design hardware boards, and a software High Level Trigger. A new Level-1 trigger architecture with improved performance is now being used to maintain high physics efficiency for the more challenging luminosity conditions experienced during Run II.

 Measurements of the CMS jet energy scale and resolution at 13 TeV / Dordevic, Milos (VINCA Inst. Nucl. Sci., Belgrade) /CMS Collaboration Jets are the experimental signatures of energetic quarks and gluons produced in high energy processes and they need to be calibrated in order to have the correct energy scale. A detailed understanding of both the energy scale and the transverse momentum resolution of jets at the CMS experiment is of crucial importance for many physics analyses.

 Serenity - An ATCA prototyping platform for CMS Phase-2 / Rose, Andrew (Imperial Coll., London) /CMS Collaboration Serenity is an ATCA prototyping platform designed to explore alternative, novel design choices for CMS Phase-2. It uses a newly available interconnect technology from Samtec (Z-RAY) to mount a removable processing unit (FPGA) that should mitigate risk and provides significant flexibility in processing unit choice and connectivity.

 Design and performance of the upgrade of the CMS L1 trigger / Davignon, Olivier (Bristol U.) /CMS Collaboration During its second run of operation, the LHC delivered proton-proton collisions at a centre-of-mass energy of 13 TeV with a peak instantaneous luminosity larger than $2 \cdot 10^{34}$ cm$^{-2}$s$^{-1}$, more than double the peak luminosity reached during Run1 and far larger than the design value. The upgraded CMS Level-1 trigger is designed to improve the performance at high luminosity and large number of simultaneous inelastic collisions per crossing (pile-up).

 Aging studies of the triple-GEM detectors for future upgrades of the CMS muon high rate region at the HL-LHC / Fallavollita, Francesco (CERN) /CMS Collaboration The high-luminosity LHC (HL-LHC) upgrade is setting a new challenge for particle detection technologies. In the CMS muon system based on gas detectors, the increased luminosity will yield a ten times higher particle background compared to the present LHC conditions.

 Heavy flavor spectroscopy and exotic states at LHC / Sur, Nairit (TIFR, Mumbai, DHEP) /ATLAS, CMS and LHCB Collaborations The proton proton collision data collected at high centre of mass energies in the Large Hadron Collider provide an excellent environment for precision spectroscopy studies of beauty and charm hadrons. The general purpose experiments, ATLAS and CMS, and the forward-spectrometer experiment LHCb have investigated many interesting aspects of hadron spectroscopy over the years.

 Operational Experience with the CMS Hadron Forward Calorimeters Phase I Upgrade / Bilki, Burak (Iowa U.) ; Onel, Yasar (Iowa U.) ; Gulmez, Erhan (Bogazici U.) The Phase I Upgrade of the CMS Hadron Forward Calorimeters was completed during the Extended Year End Technical Stop of 2016 - 2017. In the framework of the upgrade, the front-end electronics were replaced and the PMT boxes were reworked to implement two-channel readout in order to exploit the benefits of the multi-anode PMTs.
