Abstract

The HypHI experiment for precise hypernuclear spectroscopy with induced reactions of stable heavy ion beams and rare isotope beams is currently under preparation at GSI. The main goal of the HypHI project is to study neutron and proton rich hypernuclei and to measure directly hypernuclear magnetic moments at GSI and FAIR. In the first HypHI experiment (Phase 0) planned in 2009, the feasibility of precise hypernuclear spectroscopy with heavy ion beams will be demonstrated by observing pi(-) decay channels of Lambda(3)H, Lambda(4)H and Lambda(5)He with (6)Li projectiles at 2 Lambda GeV impinging on a (12)C target. An overview of the HypHI project and the details of the Phase 0 experiment will be discussed.

Summary: Hypernuclei, subatomic bound systems containing hyperons, provide a unique test ground for understanding nuclear forces and interactions between baryons with different quark flavors. Recent studies have revealed puzzling results regarding the lightest three-body hypernuclear system, the hypertriton, and the unexpected existence of a bound state of two neutrons with a hyperon. Solving these mysteries can enhance our knowledge of fundamental baryonic interactions and the interior nature of neutron stars.

Takaharu Otsuka, Noritaka Shimizu, Yusuke Tsunoda

Summary: The ground-state properties of neutron-rich exotic Na and Mg isotopes with even numbers of neutrons, N, are studied up to drip lines. The shell-model calculations with an ab initio effective nucleon-nucleon interaction reported by Tsunoda, Otsuka, Takayanagi et al. are extended to observables such as magnetic dipole and electric quadrupole moments, and charge and matter radii. Good agreements with experimental data are found, and predictions are shown up to drip lines.

First Simultaneous Acceleration of Multiple Charge States of Heavy Ion Beams in a Large-Scale Superconducting Linear Accelerator

P. N. Ostroumov, K. Fukushima, T. Maruta, A. S. Plastun, J. Wei, T. Zhang, Q. Zhao

Summary: The experimental studies focused on the simultaneous acceleration of three-charge-state Xe-129(49)+, 50+(,51+) beam from 17 to 180 MeV/nucleon in a superconducting linear accelerator. The results showed that recombination of three charge states in the six-dimensional phase space increased the xenon beam intensity by 2.5-fold compared to the single-charge-state beam, validating the potential to produce and utilize high-quality multiple-charge-state heavy-ion beams in a large-scale superconducting linac to increase beam power for isotope production targets.

Application of Accelerator Beam Dumps for Dark Matter Searches

Patrick Achenbach, Mirco Christmann

Summary: Light dark matter is an attractive candidate for the majority of the universe's mass, and beam dump experiments at high-intensity accelerators are powerful tools for producing and detecting it. The DarkMESA experiment will run behind the dump of the 150-MeV electron beam, while the Beam Dump eXperiment (BDX) is proposed to run behind the Jefferson Lab Hall-A beam dump, both using similar detector concepts to probe the direct scattering reactions of light dark matter.

Summary: We present the first measurement of the DVCS beam-spin asymmetry using the CLAS12 spectrometer, with a 10.2 and 10.6 GeV electron beam scattering from unpolarized protons. Our results significantly expand the Q2 and Bjorken-x phase space beyond existing data in the valence region, providing 1600 new data points with unprecedented statistical uncertainty. These findings set new, tight constraints for future phenomenological studies.

Walcher, A. Weber

Summary: We conduct a comprehensive study on the alpha-particle excitation process from its ground state to the resonance state. By performing an electron scattering experiment, we investigate the monopole transition form factor in a wide range of Q2 values. The newly obtained data show significantly higher precision compared to previous data sets, enabling the determination of two coefficients in a low-momentum expansion and revealing a new puzzle. Our experimental results, when compared to state-of-the-art theoretical calculations, indicate a failure of modern nuclear forces, including those derived from chiral effective field theory.

Summary: We report the first measurements of the multiplicity ratio and transverse momentum broadening as a function of energy fraction in hyperon production in semi-inclusive deep-inelastic scattering off different targets. These results show a strong suppression at high energy fraction and an enhancement at low energy fraction. The observed transverse momentum broadening is much larger than that of light mesons, indicating a strong interaction between the propagating entity and the nuclear medium.

Summary: In this study, we updated the analysis of τ lepton decays into a light charged lepton and a vector meson using data collected with the Belle detector at the KEKB collider. No significant excess of signal events was observed, and thus upper limits were set on the τ -> lV(0) branching fractions at the 90% credibility level, ranging from (1.7- 4.3) x 10(-8). These limits show an average improvement of 30% compared to previous results.

A Deep-Learning-Computed Cancer Score for the Identification of Human Hepatocellular Carcinoma Area Based on a Six-Colour Multiplex Immunofluorescence Panel

Summary: Liver cancer, particularly hepatocellular carcinoma (HCC), is a common and deadly form of cancer worldwide. Numerous studies have examined the impact of immune infiltrates on cancer patient prognosis, but accurately delineating the cancer area has been challenging due to heterogeneity and operator variability. However, advancements in multiplex analyses and machine learning techniques offer potential for objective identification of cancer areas and analysis of prognostic immune parameters.

Summary: A novel technique has been developed to study bound states of exotic hadrons in subatomic nuclei, using the Fragment Separator FRS and the WASA central detector at GSI. Two recent experiments were conducted, S447 for studying light hypernuclei and S490 for searching for mesic-nuclei. Data analyses are currently underway, and clear observations and identifications of light charged particles have been made in both experiments.

Summary: In this study, we measured the lifetime of the D-s(+) meson using data collected by the Belle II experiment at the SuperKEKB collider. By fitting the decay-time distribution of D-s(+)->phi pi+ decays, we determined that the lifetime of the D-s(+) meson is tau(+)(Ds)=(499.5 +/- 1.7 +/- 0.9) fs, with improved precision compared to previous measurements.

Summary: This study presents the first measurement of the ratio of branching fractions of inclusive semileptonic B-meson decays, which is a precision test of electron-muon universality. The results obtained using data collected by the Belle II detector show that the measured ratio is in agreement with the standard-model expectation, making it the most precise lepton-universality test of its kind.

Summary: This paper reports the first measurement of the Michel parameter ξ0 using a new method. The result obtained from analyzing the data collected by the Belle detector is consistent with the prediction of the standard model. Our study demonstrates the practicality of this method and provides a basis for further precise measurements in future experiments.

Summary: In this study, we measured CP asymmetries and branching-fraction ratios for B± → DK± and B± → Dπ± decays. The results provide model-independent information on the angle phi(3) of the unitarity triangle.

Summary: The WASA-FRS experiment aims to reveal the nature of light A hypernuclei with heavy-ion beams. The lifetimes of hypernuclei are measured precisely from their decay lengths and kinematics. In this study, a machine learning analysis method with a graph neural network (GNN) was developed to obtain track associations and accurately identify p(-) mesons emitted from hypernuclear decay. The developed GNN model achieved a 98% tracking efficiency and accurately estimated the charge and momentum of the particles of interest, with a 99.9% identification rate for negative charged particles and a momentum accuracy of 6.3%.
