 Searches for vector-like quarks and resonances decaying to top quarks with the ATLAS and CMS detectors / Van Onsem, Gerrit Patrick (DESY) /ATLAS and CMS Collaborations Many models beyond the standard model predict the existence of vector-like quarks or other types of heavy resonances. Using proton-proton collision data at center-of-mass energies of 8 and 13 TeV, the ATLAS and CMS Collaborations have performed a multitude of searches for pair and singly produced vector-like quarks decaying to W, Z, or Higgs bosons.

 Measurement of normalized differential $t\bar{t}$ cross sections in the dilepton channel from pp collisions at 13 TeV / Roh, Youn (Korea U.) /CMS Collaboration Measurements of normalized differential cross sections for top quark pair production are performed in the dilepton decay channels in proton-proton collisions at a center-of-mass energy of 13~TeV. The differential cross sections are measured with data corresponding to an integrated luminosity of 2.1~fb$^{-1}$ recorded by the CMS experiment at the LHC.

 Measurements of differential $t\bar t$ cross sections at CMS / Hindrichs, Otto Heinz (Rochester U.) /CMS Collaboration An overview of recent measurements of differential top quark pair production cross sections performed by the CMS experiment at the LHC is presented. Measurements at different proton-proton center-of-mass energies are available using the dilepton, lepton+jets, and all-jets decay channels of the top quark.

 Review of the latest measurements of the inclusive $\mathrm{t\bar t}$ production cross section in CMS / Gonzalez Fernandez, Juan Rodrigo (Oviedo U.) /CMS Collaboration The measurement of the $\mathrm{t\bar t}$ inclusive production cross section $\sigma_{t\bar t }$ is crucial to probe QCD predictions, constrain new physic scenarios, proton PDFs, top quark pole mass, $\alpha_S$ and many other parameters from the SM. The CMS Collaboration has measured this quantity in different final states and at different centre-of-mass energies, probing QCD calculations and deriving several constraints.

 Measurement of the $\mathrm{t\bar t}$ inclusive production cross section at 5.02 TeV / Gonzalez Fernandez, Juan Rodrigo (Oviedo U.) /CMS Collaboration The top quark pair production $\sigma_{t\bar t}$ is measured in pp collisions at a center-of-mass energy of 5.02 TeV. The analyzed data have been collected by the CMS experiment at the CERN LHC and correspond to an integrated luminosity of 27.4 /pb. [...] CMS-CR-2018-005.- Geneva : CERN, 2018 - 6 p.

 Electronics and triggering challenges for the CMS High Granularity Calorimeter / Lobanov, Artur (Ecole Polytechnique) /CMS Collaboration The High Granularity Calorimeter (HGCAL), presently being designed by the CMS collaboration to replace the CMS endcap calorimeters for the High Luminosity phase of LHC, will feature six million channels distributed over 52 longitudinal layers. The requirements for the front-end electronics are extremely challenging, including high dynamic range (0-10 pC), low noise (~2000e- to be able to calibrate on single minimum ionising particles throughout the detector lifetime) and low power consumption (~10mW/channel), as well as the need to select and transmit trigger information with a high granularity.

 The front-end data conversion and readout electronics for the CMS ECAL upgrade / Mazza, Gianni (INFN, Turin) /CMS Collaboration The High Luminosity LHC (HL-LHC) will require a significant upgrade of the readout electronics for the CMS Electromagnetic Calorimeter (ECAL). The Very Front-End (VFE) output signal will be sampled at 160 MS/s (i.e. [...] CMS-CR-2017-443.- Geneva : CERN, 2017 - 8 p.

 The CMS High Granularity Calorimeter for HL-LHC / Mastrolorenzo, Luca (Aachen, Tech. Hochsch.) /CMS Collaboration The High Luminosity LHC (HL-LHC) will integrate 10 times more luminosity than the LHC, posing significant challenges for radiation tolerance and event pileup on detectors, especially for forward calorimetry, and hallmarks the issue for future colliders. As part of its HL-LHC upgrade program, the CMS collaboration is designing a High Granularity Calorimeter to replace the existing endcap calorimeters.

 Prospects for a precision timing upgrade of the CMS PbWO crystal electromagnetic calorimeter for the HL-LHC / Massironi, Andrea (Northeastern U.) /CMS Collaboration The upgrade of the Compact Muon Solenoid (CMS) crystal electromagnetic calorimeter (ECAL), which will operate at the High Luminosity Large Hadron Collider (HL-LHC), will achieve a timing resolution of around 30 ps for high energy photons and electrons. In this talk we will discuss the benefits of precision timing for the ECAL event reconstruction at HL-LHC. [...] CMS-CR-2017-430.- Geneva : CERN, 2017 - 7 p.

 A modern and versatile data-acquisition package for calorimeter prototypes test-beams H4DAQ / Marini, Andrea Carlo (MIT) /CMS Collaboration The upgrade of the calorimeters for the HL-LHC or for future colliders requires an extensive programme of tests to qualify different detector prototypes with dedicated test beams. A common data-acquisition system (called H4DAQ) was developed for the H4 test beam line at the North Area of the CERN SPS in 2014 and it has since been adopted by an increasing number of teams involved in the CMS experiment and AIDA groups.
