For the AMBER (NA66) experiment several upgrades of the COMPASS (NA58) spectrometer are foreseen for the medium and long-term AMBER program. Among this R&D; program the replacement of a part of the Multi-Wire Proportional Chambers (MWPCs) is planned, to face up the aging of some of the structural elements of the MWPC chambers. [...]

Measurement of the hard exclusive $\pi^{0}$ muoproduction cross section at COMPASS / COMPASS Collaboration
A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality $Q^2$ ranging from 1 to 8 (GeV/$c$)$^{\rm\, 2}$ and the Bjorken variable $x_{\rm Bj}$ ranging from 0.02 to 0.45. [...]

Multiplicities of positive and negative pions, kaons, and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target / COMPASS Collaboration
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 $z$. Data were obtained by the COMPASS Collaboration using a 160 GeV muon beam of both electric charges and a liquid hydrogen target. [...]

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.

High-Statistics Measurement of Collins and Sivers Asymmetries for Transversely Polarized Deuterons / COMPASS Collaboration
New results are presented on a high-statistics measurement of Collins and Sivers asymmetries of charged hadrons produced in deep inelastic scattering of muons on a transversely polarised $^6$LiD target. The data were taken in 2022 with the COMPASS spectrometer using the 160 \gevv muon beam at CERN, balancing the existing data on transversely polarised proton targets. [...]

Final COMPASS results on the transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan process / COMPASS Collaboration
The COMPASS Collaboration performed measurements of the Drell-Yan process in 2015 and 2018 using a 190 GeV/c $\pi^{-}$ beam impinging on a transversely polarised ammonia target. Combining the data of both years, we present final results on the amplitudes of the five azimuthal modulations in the dimuon production cross section. [...]
