The DAQ and clock distribution system of CMS MIP Timing Detector
/ Simkina, Polina (IRFU, Saclay)
/CMS Collaboration
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase-II upgrade program to cope with the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing detector is designed to measure minimum ionizing particles (MIPs) with a time resolution of 30-60 ps during the entire HL-LHC phase. [...]

YSF: ttH and tH production in multilepton channels with CMS experiment
/ Ramon Alvarez, Clara (Oviedo U.)
/CMS Collaboration
We measure the CP structure of the Yukawa interaction between the Higgs boson ($\mathrm{H}$) and the top quark in a data sample enriched in the $\mathrm{t}\bar{\mathrm{t}}\mathrm{H}$ and $\mathrm{t}\mathrm{H}$ associated production. Using $138~\mathrm{fb}^{-1}$ of data collected in proton-proton collisions at $\sqrt{s}=$13 TeV by the CMS experiment at the CERN LHC, and targeting events where the H decays via via $\mathrm{H} \to \mathrm{W}\mathrm{W}$ or $\mathrm{H}\to\tau\tau$ and top quarks decay either leptonically or hadronically. [...]

The CMS Trigger System
/ Dordevic, Milos (VINCA Inst. Nucl. Sci., Belgrade)
/CMS Collaboration
The CMS Experiment at CERN uses a two-stage triggering system composed of the Level-1 (L1), instrumented with custom-designed hardware boards with an output rate of 100 kHz, and the High Level Trigger (HLT), streamlined version of the offline software reconstruction that runs on the computing farm, allowing to store around 1.5 kHz rate. New trigger algorithms and new features, as well as an optimized trigger menus at both L1 and HLT are mandatory in order to be able to successfully record the events at higher data loads due to increasing luminosity and pileup at the LHC in Run 3.

The CMS Tracker for the High Luminosity LHC
/ Rossi, Alessandro (INFN, Perugia ; Perugia U.)
/CMS Collaboration
The LHC machine is planning an upgrade program which will smoothly bring the instantaneous luminosity to about $5-7.5\times10^{34}$\,cm$^{-2}$s$^{-1}$, to reach an integrated luminosity of $3000-4500$\,fb$^{-1}$ by the end of 2039. This High Luminosity LHC scenario, HL-LHC, will require an upgrade program of the LHC detectors known as Phase-2 upgrade. [...]
