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. [...]

A Comparison of p-p, p-Pb, Pb-Pb Collisions in the Thermal Model: Multiplicity Dependence of Thermal Parameters / Sharma, Natasha (Panjab U., Chandigarh) ; Cleymans, Jean (UCT-CERN Res. Ctr.) ; Hippolyte, Boris (Strasbourg, IPHC) ; Paradza, Masimba (UCT-CERN Res. Ctr.)
% An analysis is made of the particle composition (hadrochemistry) of the final state in proton-proton (p-p), proton-lead (p-Pb) and lead-lead (Pb-Pb) collisions as a function of the charged particle multiplicity ($\dNchdeta$). [...]

Search for Higgs boson pair production in the $b\bar{b}WW^\ast$ decay mode at $\sqrt{s}=13$ TeV with the ATLAS detector
A search for Higgs boson pair production in the $b\bar{b}WW^\ast$ decay mode is performed in the $b\bar{b}l\nu qq$ final state using 36.1 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. [...]
