The CMS Barrel Calorimeter Processor near production (BCP V2) board evaluation
/ Goadhouse, Stephen David (Virginia U.) ; Nikitas Loukass
The Barrel Calorimeter Processor (BCP), based on ATCA blade architecture, has been developed for the readout of the electromagnetic calorimeter (ECAL) and hadron calorimeter (HCAL) subdetectors of the CMS experiment. The BCP supports 120 optical receive channels of up to 25 Gbps, 72 optical transmit channels of up to 25 Gbps, an AMD XCVU13P UltraScale+ FPGA, and an embedded AMD Zynq UltraScale+ SoC. [...]

The status of\\the CMS Muon Drift Tubes HL-LHC Upgrade and\\the Safety System for the new front-end
/ De Remigis, Paolo (INFN, Turin)
/CMS Collaboration
To sustain the unprecedented radiation and rates of HL-LHC, the readout and trigger electronics for the Drift Tubes (DT) in CMS have been upgraded.
The time digitization is implemented on the new OBDT board, and the data are streamed to the new back-end electronics, where event building and trigger primitive generation are performed.
The development of a new hardware, called MONitor for SAfety (Monsa) system, monitors and enables each single OBDT.
This report provides an update on the status of development and testing of the DT Upgrade electronics, with a focus on the newly introduced safety electronics..

Determination of the strong coupling and its running from measurements of inclusive jet production at CMS
/ Guglielmi, Valentina (Zurich U.)
/CMS Collaboration
The value of the strong coupling $\alpha_{S}$ is determined in a comprehensive analysis at next-to-next-to-leading order accuracy in quantum chromodynamics. The analysis uses double-differential cross section measurements from the CMS Collaboration at the CERN LHC of inclusive jet production in proton-proton collisions at centre-of-mass energies of 2.76, 7, 8, and 13\,TeV, combined with inclusive deep-inelastic data from HERA.

Search for new heavy resonances decaying to higgs boson pairs in boosted bbtautau final states
/ Parida, Ganesh (Wisconsin U., Madison)
/CMS Collaboration
A search is presented for massive narrow-width resonances in the mass range of $1\text{-}4.5\,\text{TeV}$ decaying into pairs of Higgs bosons (HH), using proton-proton collision data at a center-of-mass energy of $13\,\text{TeV}$ collected with the CMS detector at the LHC during the $2016\text{-}2018$ data-taking. The data correspond to an integrated luminosity of $138~\mathrm{fb}^{-1}$. [...]
