Lead Archives: Ancient Minerals vs. Higgsino ✦
Original: "Heavy-element paleodetectors for Higgsino dark matter"
Ancient lead crystals turn into natural detectors capable of catching the Higgsino for the first time — the elusive particle of inelastic dark matter.

Laurionite crystals are natural lead plates, exposed to the dark matter flux for eons. An ion microscope now reveals the hidden image. For the first time, we can catch the Higgsino — a candidate that has evaded Earth-based detectors. It's cosmic forensics: entire minerals serve as physical evidence.
🎯 Constraints on uranium content in deep brines, obtained by geophysicists in the 1980s, unexpectedly became useful decades later for paleodetector developers.
🎬 It's as if the characters of Arthur C. Clarke's 'Rendezvous with Rama' studied not an alien spaceship, but the rocks themselves — the silent witnesses of cosmic dramas.
\delta_{\max,A} = \frac{1}{2} \mu_A v_{\max}^2
δ_max,A — energy splitting threshold for a nucleus with mass number A; μ_A — reduced mass of the dark particle and nucleus; v_max — maximum velocity of dark matter particles in the laboratory frame.
