If the Vacuum Has No Wall, Where Does the Gap Live?
What two UNNS Yang–Mills projects revealed about structural accessibility, spectral discreteness, and the missing bridge between them
We began with a strong hypothesis: perhaps the Yang–Mills mass gap reflects a structural boundary that cannot be crossed as one approaches the vacuum. The data did not establish that wall. What emerged instead was more interesting: structural accessibility and a positive spectral scale can coexist.
