Analyzes diagonal GPD overlaps from light-front wave functions in the 't Hooft model, finding no linear b term in equal-mass second moments and a resonant b^4 ln^2(1/b) nonanalyticity at beta=1/2 that limits the diagonal overlap.

Light-front diagnostics in the 't Hooft model: I. Wave functions, EMT decomposition, and the diagonal GPD overlap
Analyzes diagonal GPD overlaps from light-front wave functions in the 't Hooft model, finding no linear b term in equal-mass second moments and a resonant b^4 ln^2(1/b) nonanalyticity at beta=1/2 that limits the diagonal overlap.
