About this paper

Imagine a door you can knock on forever. You knock, and no one answers. You knock again, louder, with better instruments, for decades, and still no one answers. What have you learned? In most of science, silence that deep means the room is empty. But if the room has a place in it where a person could stand and never be heard, then the silence proves nothing either way. That is the situation of neutrinoless double-beta decay, and it is the dead end this paper prices. The question underneath the experiment is a binary fact about nature: is the neutrino its own antiparticle, a Majorana particle, or a Dirac particle, distinct from its antiparticle? The flagship test built to answer it watches for a decay that can happen only if the Majorana answer is true. The KamLAND-Zen Collaboration, with its complete dataset, has now watched to extraordinary depth and found nothing: a half-life bound beyond 3.8 in units of ten to the twenty-sixth years at 90 percent confidence, with the effective Majorana mass in 28 to 122 meV, as published in Physical Review Letters 135, 262501 (2025). I credit that null at full strength: it is a measurement, not a failure, and it closes real ground. But in the normal ordering, the effective Majorana mass can cancel toward zero even if neutrinos are Majorana particles. The observable has a blind spot, and the answer may live exactly in it; the experiment can return null forever without the question being answered. My census treats this limit at its floor, and my paper The Unpaired Face treats pair-unity at the weak sector's missing-partner address. That ground is adjacent, honestly adjacent, and no more: no result in my corpus closes the blind spot, and none is claimed to. The measured toll stands NOT PRODUCED; its production form is owned as form only, at a declared input. The residue stands adopted, never derived. Grade for this dead end, printed at full size: PREMISE-ONLY. The program headline stands unmoved: vacuum catastrophe NOT SOLVED / PARTIAL, producing-count 0.
