Large-Scale Structure Probes of the Post-Inflationary Axiverse / Gorghetto, Marco (DESY) ; Trifinopoulos, Sokratis (CERN ; Zurich U.) ; Valogiannis, Georgios (Chicago U. ; Chicago U., KICP)
We study the cosmology of axions in the post-inflationary scenario, where random initial conditions and the ensuing string-domain-wall network generate an isocurvature power spectrum. [...]

Readout and testing procedures to characterize the CMS inner tracker pixel detector for HL-LHC / Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) /CMS Collaboration
The LHC will be upgraded to the High Luminosity LHC in the coming years, aiming to reach an instantaneous luminosity of up to $5 \times 10^{34}$\,cm$^{-2}$s$^{-1}$. The CMS Tracker detectors will be replaced and significantly upgraded to cope with the increased radiation fluence while ensuring excellent performance. [...]

The CMS Tracker Upgrade for Phase-2 Meeting the Challenges of the HL-LHC / Magherini, Matteo (CERN) /CMS Collaboration
The High-Luminosity Large Hadron Collider (HL-LHC) will significantly increase the instantaneous luminosity of proton-proton collisions, pushing the CMS experiment into a regime of extreme radiation levels, high particle multiplicities, and unprecedented data rates. To maintain and extend the physics performance of the CMS detector under these conditions, a complete replacement of the tracking system is underway as part of the Phase-2 Upgrade. [...]

Bare Module Testing for the CMS Vertex Detector Upgrade / Jesse Harris of the CMS collaboration /CMS Collaboration
The High-Luminosity LHC will continue exploring physics beyond the standard model with proton-proton collisions at ten times the luminosity of previous LHC runs. The physics program depends on precise measurements of charged particles near the beams. [...]

High-Throughput Packet Aggregator for the Back-End DAQ of CERN CMS HGCAL Detector / Shelake, Mukund (TIFR, Mumbai, DHEP) /CMS Collaboration
The Phase 2 upgrade of CERN LHC accelerator requires the CMS detector to replace its endcap calorimeters with the new HGCAL. Each of the 96 back-end DAQ FPGAs will process LHC collision data from 108 input optical fibre pairs operating at 10 Gb/s and will have to route the aggregated data into 12 output optical fibre pairs operating at 24 Gb/s.
