Summary: This study reports the first high-precision mass measurements of neutron-rich nuclei Ni-74, Ni-75, and the ground state of Cu-76 using the double Penning trap JYFLTRAP at the Ion Guide Isotope Separator On-Line (IGISOL) facility. The results lead to a quantitative estimation of the quenching for the N = 50 neutron shell gap. The impact of this shell quenching on core-collapse supernova dynamics is tested using a statistical equilibrium approach.

Summary: In this study, the cyclotron frequency ratio of Os-187(29+) to Re-187(29+) ions was measured with the Penning-trap mass spectrometer PENTATRAP, resulting in the most precise measurement to date. The total binding-energy difference of the 29 missing electrons in Re and Os was calculated, yielding a value of 53.5(10) eV. Finally, using the achieved results, the mass difference between neutral 187Re and Os-187, i.e., the Q value of the beta(-) decay of Re-187, was determined to be 2470.9(13) eV.

Summary: Helium-3 has become a significant candidate for research in various fields. In this study, the nuclear magnetic moment and hyperfine structure of He-3(+) were directly measured, providing a direct calibration for He-3 NMR probes and improving the precision of magnetometry by one order of magnitude. The measured values also enabled the determination of the Zemach radius with higher precision compared to previous results.

Summary: Quantum electrodynamics (QED) is a fundamental theory that has been experimentally verified to be in excellent agreement with results. A new measurement technique has been developed to directly measure the difference in g factors of highly charged ions. This technique provides accurate results and is important for validating existing theories and constraining new physics.

Summary: The Q value of the ground-state-to-ground-state beta(-)-decay from I-131 to Xe-131 was determined with high precision using the JYFLTRAP double Penning trap mass spectrometer at the IGISOL facility. The new Q value is significantly more precise and higher than previous estimations, confirming the energetically allowed beta(-)-decay to a specific excited state in Xe-131.

Summary: A double Penning trap is being commissioned at CENBG Bordeaux for the future DESIR/SPIRAL2 facility of GANIL. The setup is designed to perform both high-resolution mass separation of the ion beam for trap-assisted spectroscopy, and high-accuracy mass spectrometry of short-lived nuclides. The paper presents technical details of the new device and offline tests with the purification trap, showing a mass resolving power of about 10^5.

Summary: Developed in Python language with ROOT data analysis framework, the code presents a new phase-determination approach with up to 10 times smaller statistical uncertainties for PI-ICR mass spectrometry method. This improvement is confirmed via Monte-Carlo simulations, allowing for high-precision studies of exotic nuclear masses to test the standard model of particle physics.

Summary: This study uses the Light Gradient Boosting Machine (LightGBM) algorithm to predict the masses of unknown nuclei and explore the nuclear landscape. The refined models show significantly improved accuracy compared to the original mass models, and the predictions are in good agreement with the latest experimental data. LightGBM can be a powerful tool for refining theoretical nuclear mass models and predicting the binding energy of unknown nuclei.

Summary: Recent progress in testing Lorentz and CPT symmetry using Penning traps is summarized, including a review of quantum electrodynamics theory with Lorentz-violating operators up to mass dimensions of six. Dominant shifts in cyclotron and anomaly frequencies of confined particles and antiparticles due to Lorentz and CPT violation are derived. Results from comparisons of charge-to-mass ratios and magnetic moments of protons, antiprotons, electrons, and positrons are utilized to constrain various coefficients for Lorentz violation.

Summary: ATLAS observed a weaker-than-expected cross section for dijet resonances with a mass slightly below 1 TeV. CMS reported hints for non-resonant pair production of dijet resonances with a particle Y at a similar mass range. By reinterpreting CMS analysis using the ATLAS preferred mass range, a resonant search was conducted, finding excesses for a mass of Y around 3.6 TeV.

Summary: We propose a novel class of composite models that combine technicolor and composite Higgs vacuum limits, resulting in an asymmetric dark matter candidate. These models are based on an extended left-right electroweak symmetry with a pseudo-Nambu Goldstone boson Higgs and stable dark matter candidates charged under a global U(1)X symmetry.

Summary: The discovery of radioactivity demonstrated that energy in the nucleus can be released as kinetic energy of radioactive particles. Fission and fusion reactions generate large amounts of energy suitable for electricity generation in nuclear power plants. The binding energy associated with each nucleus determines the energy released or absorbed in these nuclear reactions. Nuclear binding energy refers to the energy required to keep protons and neutrons together in a nucleus, while nuclear power is the energy released during nuclear fission or fusion. Each nucleus has its own binding energy, which is equivalent to the energy needed to split the nucleus. The paper presents a web application for calculating nuclear binding energy per nucleon, which involves determining the mass defect and converting it into energy per nucleon.
