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.

Correction of the baseline fluctuations in the GEM-based ALICE TPC
/ ALICE TPC Collaboration
To operate the ALICE Time Projection Chamber in continuous mode during the Run~3 and Run~4 data-taking periods of the Large Hadron Collider, the multi-wire proportional chamber-based readout was replaced with gas-electron multipliers. As expected, the detector performance is affected by the so-called common-mode effect, which leads to significant baseline fluctuations. [...]

Anomalous soft photons: status and perspectives
/ Bailhache, R. (Frankfurt U., Inst. Kernphys.) ; Bonocore, D. (Munich, Tech. U.) ; Braun-Munzinger, P. (Darmstadt, EMMI) ; Feal, X. (Santiago de Compostela U., IGFAE) ; Floerchinger, S.

This report summarizes the work of the EMMI Rapid Reaction Task Force on "Real and Virtual Photon Production at Ultra-Low Transverse Momentum and Low Mass at the LHC". We provide an overview of the soft-photon puzzle, i.e., of the long-standing discrepancy between experimental data and predictions based on Low's soft-photon theorem, also referred to as "anomalous" soft photon production, and we review the current theoretical understanding of soft radiation and soft theorems.

Study of the pp-> np+ reaction at 1.25 GeV with HADES
/ Liu, T (INFN, LNS) ; Liu, T (Orsay, IPN) ; Agakishiev, G (Giessen U.) ; Agodi, C (INFN, LNS) ; Balanda, A (Jagiellonian U.) ; Bellia, G (INFN, LNS) ; Belver, D (Santiago de Compostela U.) ; Belyaev, A (Dubna, JINR) ; Blanco, A (LIP, Coimbra) ; Böhmer, M (Munich, Tech. U.) et al.
In pp collisions at 1.25 GeV kinetic energy, the HADES collaboration aimed at investigating the di-electron production related to (1232) Dalitz decay ( + ! pe+e−). In order to constrain the models predicting the cross section and the production mechanisms of resonance, the hadronic channels have been measured and studied in parallel to the leptonic channels.

/FRS-ESR ; ILIMA ; SPARC ; TBWD,
Highly charged radioactive ions can be stored for extended periods of time in storage rings which allows for precision measurements of their decay modes. The straightforward motivation for performing such studies is that fully ionised nuclei or few-electron ions can be viewed as clean quantum-mechanical systems, in which the interactions of the many electrons can be either excluded or treated precisely.
