Summary: This study develops a Monte Carlo simulation approach to describe proton-induced secondary electron emission in solids. Theoretical modeling based on the Mott's elastic scattering cross-section and Lindhard's dielectric function was used to calculate the double differential cross-section (DDCS) of excited electrons and describe electron transport in the medium. The results for aluminum show the angular and energy distributions of backscattered electrons for incident protons with energy below 25 keV at normal incidence, and the total electron emission yield also agrees well with available measurements.

Summary: The hadron particle identification provided by LHCb's RICH system is crucial for the success of the experiment, and it will continue to play a significant role in Upgrade II. To maintain the current excellent particle identification performance, substantial improvements in the precision of measuring the space and time coordinates of detected photons in the RICH and in the resolution of the reconstructed Cherenkov angle are required.

Summary: The ALICE collaboration is proposing a new apparatus, ALICE 3, to investigate the Quark Gluon Plasma (QGP) properties. In this context, conceptual studies for the development of a RICH detector for ALICE 3 are ongoing. The proposed baseline layout is a proximity-focusing RICH, using aerogel as Cherenkov radiator and Silicon Photomultipliers for photon detection. The detector specifications and performance obtained by Monte Carlo simulation are presented, along with the R&D challenges related to the design.

Summary: This paper presents the designs of the cryostats and cryogenic systems for cooling SC magnets in the SuperKEKB accelerator. The cryostats are equipped with independent cryogenic systems using a 250 W refrigerator to supply subcooled LHe and maintain stable cryogenic conditions. The cryogenic systems are designed to provide a subcooled LHe flow of -20 g/s and to handle refrigeration and liquefaction loads. The paper also discusses the operation modes, cooldown and quench of the SC magnets, and evaluates the heat leaks.

Summary: The HERMES Pathfinder mission aims to develop a constellation of nanosatellites for studying astronomical transient sources. This study presents the results of using a novel inorganic scintillator to describe the persistent luminescence of a scintillating crystal after irradiation with high energy protons and ultraviolet light. The study demonstrates the suitability of this scintillator for the HERMES Pathfinder nanosatellites based on its low contribution to the detector's input current.

Summary: We present a highly selective experimental setup for particle-γ coincidence experiments using fast CeBr3 scintillators for γ-ray detection at the Super-Enge Split-Pole Spectrograph (SE-SPS) of the John D. Fox Superconducting Linear Accelerator Laboratory at Florida State University (FSU). The characterization tests of the first five CeBr3 scintillation detectors of the CeBr3 Array (CeBrA) regarding energy resolution and timing characteristics are reported. The results of the first particle-γ coincidence experiments successfully performed with the CeBrA demonstrator and the FSU SE-SPS are also presented. It is demonstrated that the new setup allows for very selective measurements of γ-decay branching ratios and particle-γ angular correlations using narrow excitation energy gates, facilitated by the excellent particle energy resolution of the SE-SPS. Moreover, the determination of nuclear level lifetimes in the nanoseconds regime is highlighted by measuring the time difference between particle detection with the SE-SPS focal-plane scintillator and γ-ray detection with the fast CeBrA detectors. The selective excitation energy gates with the SE-SPS exclude any feeding contributions to these lifetimes.

Summary: The level density models play an important role in the de-excitation process of nuclei and have implications on various aspects such as fission fragments, neutron and gamma-ray multiplicities, and isomeric states. In this study, six currently used level density models and the spin distribution were tested by comparing calculations with measured isomeric yield ratios. The results showed a clear preference for high-spin states in all six studied models. Further investigations indicated that reducing the width of the spin distribution significantly improves the agreement between calculated and experimentally observed yield ratios.

Summary: We discuss the reconstruction of low-energy nuclear reaction kinematics using charged-particle tracks in solenoidal spectrometers operating in Active Target Time Projection Chamber mode. An algorithm based on a linear quadratic estimator (Kalman filter) is employed to infer the reaction kinematics from the three dimensional point cloud. The performance of this algorithm is evaluated using experimental data from the Active Target Time Projection Chamber (AT-TPC) detector.

Summary: In this paper, the relativistic corrections to the leading order three-nucleon (3N) contact interactions are analyzed. It is shown that the inclusion of five additional terms with fixed coefficients is required in order to describe the 3N potential in reference frames other than the center-of-mass frame, and these terms will be relevant in systems with mass number A > 3.

Summary: Resummed-Range Effective Field Theory is a nonrelativistic Effective Field Theory that investigates three identical bosons in a two-body system with one bound and one virtual state, or with two virtual states. It is found that no three-body interaction is needed to renormalize and stabilize the system at leading order, and a well-defined ground state exists in certain parameter ranges. Three-body excitations appear near the quasi-unitarity point and obey discrete scaling relations. The trajectories of the ground state and lowest three excitations are explored, as well as the discrete scale invariance in the Short-Range EFT.

The validity of these relations is confirmed through a thorough comparison with experimental data.
