FlashSim prototype: an end-to-end fast simulation using
Normalizing Flow
/ Vaselli, Francesco (INFN, Pisa ; Pisa, Scuola Normale Superiore) ; Rizzi, Andrea (INFN, Pisa ; Pisa U.) ; Cattafesta, Filippo (INFN, Pisa) ; Cicconofri, Gloria (INFN, Pisa)
/CMS Collaboration
We present a prototype of Flash-sim, a fast simulation for CMS analysis level event
content (NANOAOD) based on Machine Learning. The Normalizing Flow technique
is used to directly simulate reconstructed physics object information from generator
level objects, skipping the full simulation and reconstruction [...]

Evaluation of HPK $n^+$-$p$ planar pixel sensors for the CMS Phase-2 upgrade
/ The Tracker Group of the CMS Collaboration
/CMS Collaboration
To cope with the challenging environment of the planned high luminosity upgrade
of the Large Hadron Collider (HL-LHC), scheduled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determined by the long operation time of 10~years with an instantaneous peak luminosity of up to
$7.5\times 10^{34}$~cm$^{-2}$s$^{-1}$ in the ultimate performance scenario.
Depending on the radial distance from the interaction point, the silicon sensors will receive a particle fluence corresponding to a non-ionizing energy loss of up to $\Phi_{\text{eq}} = 3.5\times 10^{16}$~cm$^{-2}$. [...]

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 [...]

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. [...]
