With Nick Rodd, Tracy Slatyer, & Linda Xu: possible tension with LZ and higgsinos arxiv.org/abs/2609.04175
If the LZ event is from a thermal higgsino, you would also expect events in the high-energy sideband, but LZ reports none. The collaboration can definitively check this with their acceptance.

Confronting the Higgsino Interpretation of the LZ Event with the High-Energy Sideband
The LZ experiment has reported a single 248 keV nuclear recoil event in their $2.84$ ton-yr exposure on a xenon target. The absence of lower nuclear recoil events is naturally explained by inelastical...
