Neutrino Rate Predictions for FASER
/ FASER Collaboration
The Forward Search Experiment (FASER) at CERN's Large Hadron Collider (LHC) has recently directly detected the first collider neutrinos. Neutrinos play an important role in all FASER analyses, either as signal or background, and it is therefore essential to understand the neutrino event rates. [...]

/ Solans Sánchez, C (CERN) ; Allport, P (Birmingham U.) ; Asensi Tortajada, I (CERN) ; Berlea, D V (Oslo U.) ; Bortoletto, D (Oxford U.) ; Dachs, F (CERN) ; Dao, V (CERN) ; Denizli, H (Abant Izzet Baysal U.) ; Dobrijevic, D (CERN ; Zagreb U.) ; Dyndal, M (CERN) et al.
Depleted Monolithic Active Pixel Sensors are of highest interest at the HL-LHC and beyond for the replacement of the Pixel trackers in the outermost layers of experiments where the requirement on total area and cost effectiveness is much bigger. They aim to provide high granularity and low material budget over large surfaces with ease of integration. [...]

Within the ATTRACT FASTPIX project, a monolithic pixel sensor demonstrator chip has been developed in a modified 180 nm CMOS imaging process technology, targeting sub-nanosecond timing precision for single ionising particles. It features a small collection electrode design on a 25 micrometers-thick epitaxial layer and contains 32 mini matrices of 68 hexagonal pixels each, with pixel pitches ranging from 8.66 to 20 micrometers.

Search for dark photons with the FASER detector at the LHC
/ FASER collaboration
The FASER experiment at the LHC is designed to search for light, weakly-interacting particles produced in proton-proton collisions at the ATLAS interaction point that travel in the far-forward direction. The first results from a search for dark photons decaying to an electron-positron pair, using a dataset corresponding to an integrated luminosity of $27.0~\mathrm{fb}^{-1}$ collected at center-of-mass energy $\sqrt{s} = 13.6$ TeV in 2022 in LHC Run 3, are presented.
