“…The definition of the energy spectrum of reactor antineutrinos is problematic. The results of Daya Bay, Double Chooz, RENO show a spectrum which deviates from the paradigmatic spectral prediction of [32,55,56] in the energy range 4-6 MeV: this deviation is called 5 MeV excess. Borexino calculated the spectrum of antineutrinos with and without the 5 MeV excess.…”

The review is conceived to provide a useful toolbox to understand present geoneutrino results with a view to shed light on Earth's energetics and composition. The status of the geoneutrino field is presented starting from the comprehension of their production, propagation, and detection, and going on with the experimental and technological features of the Borexino and KamLAND ongoing experiments. The current understanding of the energetical, geophysical and geochemical traits of our planet is examined in a critical analysis of the currently available models. By combining theoretical models and experimental results, the mantle geoneutrino signal extracted from the results of the two experiments demonstrates the effectiveness in investigating deep earth radioactivity through geoneutrinos from different sites. The obtained results are discussed and framed in the puzzle of the diverse classes of formulated Bulk Silicate Earth models, analyzing their implications on planetary heat budget and composition. As final remarks, we turn our gaze to the prospects in the field of geoneutrinos presenting the expectations of experiments envisaged for the next decade and the engaging technological challenges foreseen.

“…In the minimal KKLT setup, α is a positive rational number [35,36]. In the literature, the phenomenology of positive α has been studied intensively particularly to resolve the fine-tuning problem to realize the electroweak (EW) symmetry breaking scale [40][41][42][43][44][45][46]. However, it is known that the muon g − 2 anomaly is hardly explained in the cases with positive α due to relatively heavy winos and bino.…”

The new measurement of the anomalous magnetic momentum of muon at the Fermilab Muon g − 2 experiment has strengthened the significance of the discrepancy between the standard model prediction and the experimental observation from the BNL measurement. If new physics responsible for the muon g − 2 anomaly is supersymmetric, one should consider how to obtain light electroweakinos and sleptons in a systematic way. The gauge coupling unification allows a robust prediction of the gaugino masses, indicating that the electroweakinos can be much lighter than the gluino if anomaly-mediated supersymmetry breaking is sizable. As naturally leading to mixed modulus-anomaly mediation, the KKLT scenario is of particular interest and is found capable of explaining the muon g − 2 anomaly in the parameter region where the lightest ordinary supersymmetric particle is a bino-like neutralino or slepton.
