Why it is here

An independent solar-neutrino challenge to both thermal and nonthermal Higgsino interpretations.

Machine-assisted summary

The authors use atmospheric-neutrino measurements from Super-Kamiokande and IceCube to constrain Higgsinos captured in the Sun, reporting a lower splitting bound near 557 keV that disfavors standard-halo Higgsino explanations of the LZ event.
