Silicon vertex detector with timing for the Upgrade II of LHCb / Rodríguez Rodríguez, Efrén (Santiago de Compostela U., IGFAE) /LHCb Collaboration
LHCb has recently submitted a physics case for an Upgrade II detector to begin operation in 2031. The upcoming upgrade is designed to run at instantaneous luminosities of 1.5×1034cm−2s−1, to accumulate a data sample with a corresponding integrated luminosity of over 300fb−1. [...]

The TORCH time-of-flight detector / Harnew, N (Oxford U.) ; Gao, R (Oxford U.) ; Hadavizadeh, T (Oxford U.) ; Hancock, T H (Oxford U.) ; Smallwood, J C (Oxford U.) ; Brook, N H (Bath U.) ; Bhasin, S (Bristol U.) ; Cussans, D (Bristol U.) ; Rademacker, J (Bristol U.) ; Forty, R (CERN) et al.
TORCH is a large-area time-of-flight (ToF) detector, proposed for the Upgrade-II of the LHCb experiment. It will provide charged hadron identification over a 2–20 GeV/c momentum range, given a 9.5m flight distance from the LHC interaction point. [...]

Performance of improved RPCs demonstrator for the CMS at the HL-LHC / Asilar, Ece (Hanyang U.) /CMS Muon Collaboration
With the increase of the LHC luminosity foreseen in the coming years, components of detectors currently used in the LHC need to be replaced or new ones should be added. The new ones should be capable not only to support the high particle rate, but also to provide time information to reduce the data ambiguity due to the expected high pileup. [...]

$B^0_s \to J/\psi \phi$ in ATLAS / Thaler, Alexander (Innsbruck U.) /ATLAS Collaboration
A measurement of the $B^0_s \to J/\psi \phi$ decay parameters using $80.5\,\mathrm{fb}^{-1}$ of integrated luminosity collected with the ATLAS detector from $13\,\mathrm{TeV}$ proton-proton collisions at the LHC is presented. The measured parameters include the CP-violating phase $\phi_s$, the width difference $\Delta\Gamma_s$ between the $B^0_s$ mass eigenstates and the average decay width $\Gamma_s$..

Experimental status of $b \to s \{\gamma, e^+e^-, \mu^+\mu^-\}$ at the LHC / Henderson, Riley (Monash U.) /ATLAS Collaboration ; CMS Collaboration ; LHCb Collaboration
An overview of the status of measurements at the LHC on beauty hadron decays involving the $b \to s \{\gamma, e^+e^-, \mu^+\mu^-\}$ transitions is presented. Such decays are rare in the Standard Model and therefore particularly sensitive to potential New Physics contributions. [...]

Studies on RPC detectors operated with environmentally friendly gas mixtures in LHC-like conditions / Rigoletti, Gianluca (CERN) ; Guida, Roberto (CERN) ; Mandelli, Beatrice (CERN)
Resistive Plate Chambers (RPC) are largely employed at CERN LHC experiments thanks to their excellent trigger and timing performances. High Pressure Laminates (HPL) RPCs are operated with a gas mixture made of about 95% of C2H2F4, 5% of i-C4H10 and 0.3% of SF6. [...]

High granularity small-pad resistive micromegas for rates above MHz/cm2 / Alviggi, M (Naples U. ; INFN, Naples) ; Camerlingo, M T (Rome III U. ; INFN, Rome3) ; D'Amico, V (Rome III U. ; INFN, Rome3) ; Della Pietra, M (Naples U. ; INFN, Naples) ; Di Donato, C (Naples U. ; INFN, Naples) ; Di Nardo, R (Rome III U. ; INFN, Rome3) ; Gimmillaro, C (Rome III U.) ; Iengo, P (INFN, Trieste ; CERN) ; Iodice, M (Rome III U. ; INFN, Rome3) ; Petrucci, F (Rome III U. ; INFN, Rome3) et al.
An R&D; project has been recently started to consolidate the technology of resistive Micromegas for operations well beyond the actual operations at HEP experiments, aiming at stable, reliable, and high gain operation up to particle fluxes of the order of 10 MHz/cm2, over large surfaces. To cope with these challenges, readout copper pads, of a few mm2 size, have been proposed to reduce the occupancy of the readout elements, calling for innovative solutions for the spark protection resistive scheme.

An environmental monitoring and control system for the ATLAS ITk Outer Barrel quality control and integration / Alvarez, Diego (CERN) ; Joos, Hans L (CERN ; Gottingen U.) ; Kühn, Susanne (CERN) ; Pacifico, Nicola (CERN) ; Pettersen, Jarl N (CERN) ; Pons, Xavier (CERN) ; Vormwald, Benedikt (CERN)
This paper describes the development of a system based on Programmable Logic Controllers (PLC) for safety interlocking and environmental monitoring during ATLAS ITk Outer Barrel (OB) loaded local support quality control (QC) and later integration. The system has been developed at CERN with a focus on scalability, maintainability and reliability, and is expected to be deployed at the different ITk OB loading and integration sites..

Upgrade of the first-level muon trigger for the ATLAS experiment at the HL-LHC / Cieri, Davide (Munich, Max Planck Inst.) /ATLAS Collaboration
The HL-LHC upgrade will significantly extend the collider’s physics reach with the increased luminosity, and it poses challenging requirements on the performance of the detector, accordingly. To exploit its full physics potential, more selective hardware triggers are required. [...]

ATLAS ITk tracking and readout performance / Bortoletto, D (Oxford U.) /ATLAS ITK Collaboration
The ATLAS Inner Detector will be replaced with a new all-silicon Inner Tracker (ITk) designed for the challenging environment of the High Luminosity LHC (HL-LHC). The ITk layout of the pixel detector was recently successfully optimized to improve tracking performance and object reconstruction. [...]
