Predictions for neutrinos and new physics from forward heavy hadron production at the LHC / Buonocore, Luca (Zurich U.) ; Kling, Felix (DESY) ; Rottoli, Luca (Zurich U.) ; Sominka, Jonas (Hamburg U.)
Scenarios with new physics particles feebly interacting with the Standard Model sector provide compelling candidates for dark matter searches. Geared with a set of new experiments for the detection of neutrinos and long-lived particles the Large Hadron Collider (LHC) has joined the hunt for these elusive states. [...]

Dark Matter in ATLAS and CMS / Sahu, Bisnupriya (Hyderabad U.) ; Gomber, Bhawna (Hyderabad U.) /ATLAS Collaboration ; CMS Collaboration
The ATLAS and the Compact Muon Solenoid (CMS) used the proton-proton collision data with a center-of-mass energy of 13 TeV collected by the Large Hadron Collider (LHC) to carry out numerous searches for the existence of dark matter. This report mainly focuses on the Run II results of the independent dark matter searches using CMS and ATLAS detectors with the integrated luminosity of 139 fb$^{-1}$..

Chebyshev and Backus-Gilbert reconstruction for inclusive semileptonic $B_{(s)}$-meson decays from Lattice QCD / Barone, Alessandro (U. Mainz, PRISMA ; Southampton U.) ; Hashimoto, Shoji (KEK, Tsukuba ; Sokendai, Tsukuba) ; Jüttner, Andreas (Southampton U. ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba ; KMI, Nagoya) ; Kellermann, Ryan (KEK, Tsukuba ; Sokendai, Tsukuba)
We present a study on the nonperturbative calculation of observables for inclusive semileptonic decays of $B_{(s)}$ mesons using lattice QCD. We focus on the comparison of two different methods to analyse the lattice data of Euclidean correlation functions, specifically Chebyshev and Backus-Gilbert approaches. [...]

RD50-MPW: a series of monolithic High Voltage CMOS pixel chips with high granularity and towards high radiation tolerance / CERN-RD50 Collaboration
A series of monolithic High Voltage CMOS (HV-CMOS) pixel sensor prototypes have been developed by the CERN-RD50 CMOS working group for potential use in future high luminosity experiments. The aim is to further improve the performance of HV-CMOS sensors, especially in terms of pixel granularity, timing resolution and radiation tolerance. [...]

Analysis of discharge events in the CMS GE1/1 GEM detectors in presence of LHC beam / Calzaferri, S (INFN, Pavia) /CMS Muon Collaboration
In July 2022, the experiments installed on the Large Hadron Collider (LHC) accelerator ring started a new data taking phase, Run-3. Before this period, an upgrade campaign took place during the so called Long Shutdown 2 (2018–2022). [...]

Chips for calibration of the ATLAS Liquid Argon calorimeter / Raux, L (Ec. Polytech., OMEGA) /ATLAS Liquid Argon calorimeter calibration Group Collaboration
The LHC upgrade requires redoing the liquid Argon (LAr) calibration system which should provide a 16-bit range signal with 1‰ accuracy while being radiation tolerant. The fundamental operating principle remains unchanged: a precise current is stored in an inductor, and upon switching off the current, a pulse is generated for injection into the readout electronics.

Validation of the 65 nm TPSCo CMOS imaging technology for the ALICE ITS3 / Ferrero, C (Polytech. Turin ; INFN, Turin) /ALICE Collaboration
During the next Long Shutdown (LS3) of the LHC, planned for 2026, the innermost three layers of the ALICE Inner Tracking System will be replaced by a new vertex detector composed of curved ultra-thin monolithic silicon sensors. The R&D; initiative on monolithic sensors of the CERN Experimental Physics Department, in cooperation with the ALICE ITS3 upgrade project, prepared the first submission of chip designs in the TPSCo 65 nm technology, called MLR1 (Multi Layer Reticle).

Data transmission architecture of the ALICE ITS3 stitched sensor prototype MOSAIX / Dorosz, P (CERN) /MOSIAX design Team Collaboration ; ALICE Collaboration
The ALICE Collaboration will replace the three innermost layers of the Inner TrackerSystem (ITS) at the LHC with an innovative vertex detector. A single-die stitched monolithic pixeldetector segment of 1.85 cm × 26.6 cm designed in 65 nm CMOS imaging technology will beused as a building block for these layers. [...]

Reliability run and data analysis of the accelerated aging of present and future electrolytic capacitors installed in the protection systems of superconducting magnets of the Large Hadron Collider at CERN / Guasch-Martínez, J (CERN) ; Carrillo, D (CERN) ; de Nicolás, E (CERN) ; Bjorkhaug, E (CERN) ; Nowak, E (CERN) ; Pojer, M (CERN) ; Rodríguez-Mateos, F (CERN)
This study evaluates the lifetime and aging process of the aluminium electrolytic capacitors to be used in the new protection systems of the High Luminosity LHC superconducting magnets. The accelerated testing and analysis of several groups of capacitors aged for more than one year provided insights into their expected lifespan and aging process. [...]
