   Over the past few decades, the study of singly heavy baryons has entered a golden era, with numerous excited states observed by experimental collaborations. Various theoretical approaches have been developed to investigate their properties, with the QCD sum rule method being one of the most widely applied. This paper provides a review of these QCD sum rule studies. Over the last ten years, we have systematically studied $P$-wave singly heavy baryons using QCD sum rules and light-cone sum rules within the framework of heavy quark effective theory. These $P$-wave singly heavy baryons can explain many excited heavy baryons, including the ${\Lambda }_c(2595{)}^{+}$, ${\Lambda }_c(2625{)}^{+}$, ${\Xi }_c(2790{)}^{0/+}$, ${\Xi }_c(2815{)}^{0/+}$, ${\Sigma }_c(2800{)}^0$, ${\Xi }_c(2882{)}^0$, ${\Xi }_c(2923{)}^0$, ${\Xi }_c(2939{)}^0$, ${\Xi }_c(2965{)}^0$, ${\Omega }_c(3000{)}^0$, ${\Omega }_c(3066{)}^0$, ${\Omega }_c(3090{)}^0$, ${\Omega }_c(3050{)}^0$, ${\Omega }_c(3119{)}^0$, ${\Lambda }_b(5912{)}^0$, ${\Lambda }_b(5920{)}^0$, ${\Xi }_b(6087{)}^0$, ${\Xi }_b(6095{)}^0/{\Xi }_b(6100{)}^{-}$, ${\Sigma }_b(6097{)}^{\pm }$, ${\Xi }_b(6227{)}^{-}$, ${\Omega }_b(6316{)}^{-}$, ${\Omega }_b(6330{)}^{-}$, ${\Omega }_b(6340{)}^{-}$, and ${\Omega }_b(6350{)}^{-}$, etc. Furthermore, we predict additional $P$-wave singly heavy baryons, including two ${\Lambda }_b$ states, two ${\Xi }_b$ states, three ${\Sigma }_b$ states, three ${\Xi }_b^{\prime }$ states, two ${\Omega }_b$ states, two ${\Lambda }_c$ states, two ${\Xi }_c$ states, three ${\Sigma }_c$ states, and one ${\Omega }_c$ state, all with relatively narrow decay widths, making them viable candidates for experimental observation. The study of singly heavy baryons is closely related to two meaningful questions:"What is the shortest possible lifetime of an observable particle?" and "How can one generally describe approximate (flavor) symmetries?".

   Phenomenology of light baryon resonances

   Michael Döring🇺🇸

   Protons and neutrons are the building blocks of matter, glued together in nuclei by strong interactions. They can be excited by pions, real and virtual photons, neutrinos and other probes. These excitations are referred to as light baryon resonances. A short, pedagogical overview of the field is presented including experimental progress, interpretation of light baryon resonances, and a focus on analysis methods to extract the resonance spectrum from data.

   The BUTTON-30 detector is a 30-tonne technology demonstrator designed to evaluate the potential of hybrid event detection, simultaneously exploiting both Cherenkov and scintillation light to detect particles produced in neutrino interactions. The detector is installed at a depth of 1.1 km in the Boulby Underground Laboratory allowing to test the performance of this new technology underground in a low background environment. This paper describes the design and construction of the experiment.

   Recent progress on interstellar radionuclides on Earth and the Moon

   Dominik Koll · Sebastian Fichter · Michael Hotchkis · Martin Martschini · Silke Merchel · Stefan Pavetich · Annabel Rolofs · Steve Tims · Sebastian Zwickel · Anton Wallner🇦🇺

   The detection of interstellar radionuclides in geological archives provides insights into nucleosynthesis in stars and stellar explosions as well as interstellar medium dynamics in the Local Bubble and the Local Interstellar Cloud. In this work, current projects to detect interstellar radionuclides with accelerator mass spectrometry will be reviewed. These projects aim to address unsolved questions regarding the timing and the origin of the influxes and to establish new radionuclides for future searches. For the first time, experimental evidence for an inhomogeneous deposition of interstellar 60Fe onEarthwill be presented and another potential source for 60Fe on Earth and the Moon, primary galactic cosmic rays, will be introduced.
