/ATLAS Collaboration
In April 2023 HEPScore23, the new benchmark based on HEP specific applications, was adopted by WLCG, replacing HEP-SPEC06. As part of the transition to the new benchmark, the CPU core power published by the sites needed to be compared with the effective power observed while running ATLAS workloads. [...]

Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target
/ Alexeev, G.D. (Unlisted) ; Alexeev, M.G. (INFN, Turin ; U. Turin (main)) ; Alice, C. (INFN, Turin ; U. Turin (main)) ; Amoroso, A. (INFN, Turin ; U. Turin (main)) ; Andrieux, V.

The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable $x$, the relative virtual-photon energy $y$ and the fraction of the virtual-photon energy transferred to the final-state hadron $z$.

Design and Testing of a new Tracking System for the Proton Charge Radius Measurement with the AMBER Experiment at CERN
/ Alexeev, M G (Turin U. ; INFN, Turin) ; Alice, C (Turin U. ; INFN, Turin) ; Amoroso, A (Turin U. ; INFN, Turin) ; Bajzek, M (Darmstadt, GSI) ; Chiosso, M (Turin U. ; INFN, Turin) ; Denisov, O (INFN, Turin ; CERN) ; Dreisbach, C (Munich, Tech. U.) ; Eichhorn, K (Munich, Tech. U.) ; Fischer, H (Freiburg U.) ; Friedrich, J M (Munich, Tech. U. ; ORIGINS, Garching) et al.
The concept of the unified tracking station designed for the proton charge-radius measurement planned at the AMBER (NA66) fixed-target experiment at CERN is presented. Composed of scintillating-fiber hodoscope and silicon-pixel detectors, it aims to provide 30 μrad angular resolution for the measurement of muons at momenta of 100 GeV with a time resolution of 1 ns at a nominal beam rate of 2×10$^6$ particles per second.

HEPScore: A new CPU benchmark for the WLCG
/ Giordano, Domenico (CERN) ; Barbet, Jean-Michel (SUBATECH, Nantes) ; Boccali, Tommaso (INFN, Pisa) ; Borge, Gonzalo Menéndez (CERN) ; Hollowell, Christopher (Brookhaven) ; Innocente, Vincenzo (CERN) ; Lampl, Walter (Arizona U.) ; Michelotto, Michele (INFN, Padua) ; Meinhard, Helge (CERN) ; Ondris, Ladislav (CERN) et al.
HEPScore is a new CPU benchmark created to replace the HEPSPEC06 benchmark that is currently used by the WLCG for procurement, computing resource pledges and performance studies. The development of the new benchmark, based on HEP applications or workloads, has involved many contributions from software developers, data analysts, experts of the experiments, representatives of several WLCG computing centres, as well as the WLCG HEPScore Deployment Task Force.

Phys. ; Dubna, JINR) ; Kovyazina, N A (Dubna, JINR) ; Panzieri, D (INFN, Turin ; Piemonte Orientale U., Novara)
We present the development and testing of a Micromegas detector prototype and its front end intended to be
a candidate for the substitutions of some of the Multiwire Proportional Chambers in the future AMBER (NA66)
experiment at CERN. Results of the test of the first small size prototype are discussed..
