Methods for off-shell Higgs boson production simulation used in CMS analyses / CMS Collaboration /CMS Collaboration
Studies of simulation methods for off-shell Higgs (H) boson production are presented. Reweighting techniques are applied to samples generated at next-to-leading order (NLO) in QCD with multiple H boson pole masses in order to approach NLO accuracy for the modeling of off-shell spectra. [...]

A Firmware-oriented Analytical Algorithm for Trigger Primitive Generation in the CMS Drift Tubes Detector for the High Luminosity LHC / The CMS Muon Drift Tubes Group
The Compact Muon Solenoid (CMS) experiment prepares its Phase-2 upgrade for the high-luminosity era of the LHC operation (HL-LHC). Due to the increase of occupancy, trigger latency and rates, the full electronics of the CMS Drift Tube (DT) chambers will need to be replaced. [...]

CMS Phase-2 Computing Model: Update Document / CMS Offline Software ; Computing
The Phase-2 upgrade of CMS, coupled with the projected performance of the HL-LHC, shows great promise in terms of discovery potential. However, the increased granularity of the CMS detector and the higher complexity of the collision events generated by the accelerator pose challenges in the areas of data acquisition, processing, simulation, and analysis [...]

The Pixel Luminosity Telescope: A detector for luminosity measurement at CMS using silicon pixel sensors / The CMS BRIL Collaboration
The Pixel Luminosity Telescope (PLT) is a silicon pixel detector dedicated to luminosity measurement at the CMS experiment at the LHC. It is located approximately 1.75 m from the interaction point and arranged into 16 ``telescopes'', with eight telescopes installed around the beam pipe at either end of the detector and each telescope composed of three individual silicon sensor planes. [...]

Comparative characterization study of LYSO:Ce crystals for timing applications / Addesa, Francesca Maria (Princeton U.) ; Barria, Patrizia (INFN, Rome) ; Bianco, Roberta (INFN, Rome) ; Campana, Mattia (INFN, Rome ; Rome U.) ; Cavallari, Francesca (INFN, Rome) ; Cemmi, A ; Cipriani, Marco (CERN) ; Dafinei, Ioan (INFN, Rome) ; Del Re, Daniele (INFN, Rome ; Rome U.) ; Diemoz, Marcella (INFN, Rome) et al.
Cerium-doped Lutetium-Yttrium Oxyorthosilicate (LYSO:Ce) is one of the most widely used Cerium-doped Lutetium based scintillation crystals. Initially developed for medical detectors it rapidly became attractive for High Energy Particle Physics (HEP) applications, especially in the frame of high luminosity particle colliders. [...]

The series of upgrades to the Large Hadron Collider, culminating in the High Luminosity Large Hadron Collider, will enable a significant expansion of the physics program of the CMS experiment. However, the accelerator upgrades will also make the experimental conditions more challenging, with implications for detector operations, triggering, and data analysis. [...]

A Study of the Single Higgs Modelling for Constraining Higgs Boson Trilinear Self-coupling in STXS (1.2) Measurements / CMS Collaboration /CMS Collaboration
This document provides a parametrization of the cross sections of the main Higgs boson (H) production modes as a function of the H trilinear self-coupling, $\lambda$, with the phase-space granularity defined by the simplified template cross section (STXS) framework at stage 1.2. The trilinear self-coupling of the Higgs boson is an important parameter in the standard model, which is weakly constrained by current measurements. [...]

Beam test performance of a prototype module with Short Strip ASICs for the CMS HL-LHC tracker upgrade / The Tracker Group of the CMS Collaboration /CMS Collaboration
The Short Strip ASIC (SSA) is one of the four front-end chips designed for the upgrade of the CMS Outer Tracker for the High Luminosity LHC. Together with the Macro-Pixel ASIC (MPA) it will instrument modules containing a strip and a macro-pixel sensor stacked on top of each other. The SSA provides both full readout of the strip hit information when triggered, and, together with the MPA, correlated clusters called stubs from the two sensors for use by the CMS Level-1 (L1) trigger system. Results from the first prototype module consisting of a sensor and two SSA chips are presented. [...]
