Analysis of 15 years of Fermi LAT data reveals a statistically significant halo-like excess in gamma rays around 20 GeV, potentially originating from dark matter annihilation. The study examines systematic uncertainties and explores implications for WIMP parameters.
A new model explains the small Higgs mass and the strong-CP problem by invoking a multiverse scenario. It predicts distinctive signals at hadronic EDM, fuzzy dark matter, and axion experiments.
