This presentation by John Kelley at the KITP meeting on October 27 discusses the observed increase in the atmospheric neutrino spectrum and the m+/m- charge ratio in the MINOS far detector. The findings suggest a corresponding increase in the TeV neutrino flux, attributed to the contributions from proton interactions leading to K+L states. The implications of this increase on neutrino physics and potential sources are explored, highlighting the importance of understanding atmospheric neutrinos in particle physics research.
