Uniform mod-Poisson convergence for Abelian square-tiled surfaces

Let Hg\mathcal{H}_g be the Hodge bundle over Mg\mathcal{M}_g, and let pgAb(k)p^{Ab}_g(k) be the probability that a random Abelian square-tiled surface in Hg\mathcal{H}_g has kk cylinders. Set

μg=log(4g3).\mu_g=\log(4g-3).

Abelian mod-Poisson conjecture. For every x>0x>0, uniformly for k{0,1,,xlog(g)}k\in\{0,1,\ldots,\lfloor x\log(g)\rfloor\}, as gg\to\infty,

pgAb(k+1)=eμgμgkk!(1Γ(t)+o(1)).p^{Ab}_g(k+1)=e^{-\mu_g}\frac{\mu_g^k}{k!}\left(\frac{1}{\Gamma(t)}+o(1)\right).

The claim predicts that cylinder statistics for Abelian square-tiled surfaces are asymptotically modeled by a mod-Poisson law; the supplied text gives no resolution status beyond presenting it as a conjecture.
