Exotics searches in CMS / Romeo, Francesco (Vanderbilt U.) /CMS Collaboration
We provide an overview of the research program dedicated to exploring exotic physics beyond the Standard Model of particle physics within the CMS Collaboration. The latest findings from searches for new physics are highlighted, using the most recent dataset collected during the Run 2 period from 2016 to 2018, featuring pp collisions at a center-of-mass energy of 13 TeV and a luminosity of about 138 fb$^{-1}$. [...]

Status and perspective of Lepton Flavor Violation at ATLAS and CMS / Aruta, Caterina (Florida U.) /ATLAS and CMS Collaborations
These proceedings collect a selection of recent experimental results on Lepton Flavor Violation (LFV) searches carried out at the ATLAS and CMS experiments at the LHC. These results are obtained by using the proton-proton collision dataset at $\sqrt{s}$ = 13 TeV, collected during the Run 2 of the LHC, and corresponding to an integrated luminosity of about 140 $\mathrm{fb^{-1}}$.\\ In the first part of these proceedings, few searches for LFV with multi-lepton final states are presented, followed by the searches for this kind of violation in the Higgs boson decays. Finally, the results from the LFV searches in the top quark sector are discussed..

Design and construction of the CMS Outer Tracker for the HL-LHC Upgrade / Roewert, Nicolas Maximilian (Aachen, Tech. Hochsch.)
The High Luminosity LHC (HL-LHC) is expected to deliver an integrated luminosity of 3000--4000\,fb$^{-1}$ with the peak instantaneous luminosity reaching to about 5--7.5$\times10^{34}\,$cm$^{-2}$s$^{-1}$. During the Long Shutdown 3 period, several components of the CMS detector will undergo major changes, called Phase-2 upgrades, to be able to operate in the challenging environment of the HL-LHC.

Jet measurements in small systems relevant for in-medium modifications / Radl, Attila Jozsef (Budapest, RMKI) /ALICE, ATLAS and CMS Collaborations
Ultrarelativistic heavy-ion collisions provide insights into the early stages of the expanding universe. The quark-gluon plasma (QGP) is a unique state of matter formed in such high-energy interactions. [...]

QCD Physics with the CMS Detector / Kodolova, Olga (Moscow State U.) /CMS Collaboration
The soft and hard QCD processes are analyzed by the CMS experiment using samples of proton-proton collisions collected by the LHC at sqrts=7, 8 and 13 TeV. Measurements of jet production rates, jet properties, particle multiplicity, particle momentum spectra and correlations are presented. The results are compared to predictions of theoretical models at leading- and next-to-leading orders of QCD. [...]

The CMS HGCAL trigger data receiver / Shukla, Raghunandan Atul (Imperial Coll., London) /CMS Collaboration
As part of the CMS Phase-2 upgrade, a prototype receiver for the HGCAL endcap front end has been implemented using the Serenity ATCA platform. The receiver firmware was developed to test the unpacking of data from the front-end endcap trigger concentrator ASIC (ECON-T) and measure its performance and stability. [...]

40 MHz Scouting for the CMS Level-1 Trigger / Giorgetti, Sabrina (INFN, Padua) /CMS Collaboration
The Level-1 trigger Data Scouting (L1DS) is a novel data acquisition system under development for the Phase-2 CMS detector at the High-Luminosity LHC (HL-LHC). Its purpose is to capture and process Level-1 trigger (L1T) information at the bunch crossing collision frequency of the LHC preceding the standard L1T selections. [...]
