R and D towards future CMS RPC upgrades / Fagot, Alexis (Gent U.) /CMS Collaboration
High pseudo-rapidity region of CMS muon system is covered only by Cathode Strip Chambers (CSC) and lacks redundant coverage despite the fact that it is a challenging region for muons in terms of backgrounds and momentum resolution. In order to maintain good efficiency for the muon trigger in this region additional RPC are planned to be installed in stations RE31 and RE41. [...]

Dark matter searches with CMS / Jeitler, Manfred (Vienna, OAW) /CMS Collaboration
The existence of dark matter, indicated by astronomical observations, is one of the main proofs of physics beyond the standard model. Despite its abundance, dark matter has not been directly observed yet. [...]

V+jets from CMS / Zhang, Fengwangdong (Brussels U.) /CMS Collaboration
This document is dedicated to recent results on the measurements of a vector boson production associated with jets (V+jets) using CMS detector experiment, with a central proton-proton (pp) collision energy of respectively 8 TeV (RunI) and 13 TeV (RunII). The vector boson can be a W boson, Z boson, or photon. [...]

Associative Memory pattern matching for L1 track trigger for the HL-LHC CMS / Fedi, Giacomo (INFN, Pisa) /CMS Collaboration
The High Luminosity LHC (HL-LHC) will deliver luminosities of up to $5 \times 10^{34}$ Hz/cm$^2$, with an average of about 140 overlapping proton-proton collisions per bunch crossing. These extreme pileup conditions place stringent requirements on the trigger system to be able to cope with the resulting event rates. [...]
