Munster) ; Antonelli, M (INFN, Trieste) ; Aresti, M (Cagliari U. ; INFN, Cagliari) ; Baccomi, R (INFN, Trieste) ; Becht, P (Heidelberg U.) ; Beolè, S (Turin U. ; INFN, Turin) ; Braach, J (CERN) ; Buckland, M D (INFN, Trieste ; Trieste U.) et al.
This article presents the design of a front-end circuit for monolithic active pixel sensors (MAPSs). The circuit operates with a sensor featuring a small, low-capacitance (< 2 fF) collection electrode and is integrated into the DPTS chip, a proof-of-principle prototype of 1.5×1.5 mm including a matrix of 32×32 pixels with a pitch of 15μm .

In the context of the CERN EP R&D; on monolithic sensors and the ALICE ITS3 upgrade, the Tower Partners Semiconductor Co (TPSCo) 65 nm process has been qualified for use in high energy physics, and adopted for the ALICE ITS3 upgrade. An Analog Pixel Test Structure (APTS) featuring fast per pixel operational-amplifier-based buffering for a small matrix of four by four pixels, with a sensor with a small collection electrode and a very non-uniform electric field, was designed to allow detailed characterization of the pixel performance in this technology.

/SND@LHC
We report the observation of neutrino interactions without final state muons at the LHC, with a significance of 6.4\,$\sigma$. A data set of proton-proton collisions at $\sqrt{s}= 13.6$\,TeV collected by \SND in 2022 and 2023 is used, corresponding to an integrated luminosity of 68.6\,fb$^{-1}$. [...]

(INFN, Milan Bicocca ; Milan Bicocca U.) et al.
For the High-Luminosity (HL-LHC) phase, the upgrade of the Compact Muon Solenoid (CMS) experiment at CERN will include a novel MIP Timing Detector (MTD). The central part of MTD, the barrel timing layer (BTL), is designed to provide a measurement of the time of arrival of charged particles with a precision of 30 ps at the beginning of HL-LHC, progressively degrading to 60 ps while operating in an extremely harsh radiation environment for over a decade.
