Solars, steriles and coherent scattering - what is new in low-energy neutrinos? — •Michael Wurm — Johannes Gutenberg Universität Mainz

Low-energy neutrinos have proven to be versatile probes for the investigation of oscillation physics and study of astrophysical neutrino sources. Only recently, Borexino has released data from its second observation phase, once again improving our understanding of the solar pp chain and providing new input data for the debate on solar metallicity. Meanwhile, the hunt for light eV-mass sterile neutrinos is proceeding: With several short-baseline oscillations experiments underway, the first results emerging are yet inconclusive on the occurrence of active-to-sterile neutrino oscillations. Most excitingly, a decades-long effort to detect the coherent elastic scattering of neutrinos on atomic nuclei came to a conclusion when in summer 2017 the COHERENT collaboration announced a first positive result.
