  - "We investigate the cosmological information in higher-order statistics of the
    cosmic microwave background (CMB) lensing convergence field for a near-term experiment
    with noise properties similar to the Simons Observatory (SO). Using a fully field-level
    forward-modeling pipeline based on ray-traced simulations from the massivenus
    suite and realistic SO-like CMB lensing reconstruction, we naturally include nonlinear
    structure formation, post-Born effects, and higher-order reconstruction noise.
    We measure several non-Gaussian statistics, including Minkowski functionals, peak
    and minima counts, moments, and wavelet-scattering coefficients. We train Gaussian-process
    emulators to model each statistic’s dependence on the matter density fraction
    Ω\U0001D45A, the scalar power spectrum amplitude \U0001D434\U0001D460, and the
    neutrino mass sum \U0001D440\U0001D708. We quantify the relative information gain
    these statistics provide beyond the lensing power spectrum and identify which
    are most robust to reconstruction noise. We find that morphology-based statistics,
    particularly Minkowski functionals and peak/minima counts, offer significant complementary
    constraining power: combining all non-Gaussian statistics with the power spectrum
    yields reductions of 40% and 38% in the marginalized uncertainties on Ω\U0001D45A
    and \U0001D434\U0001D460, respectively, and a 70% reduction in the one-sided uncertainty
    on \U0001D440\U0001D708. These gains remain non-negligible even when the power
    spectrum is extended to larger scales and combined with primary CMB and BAO data,
    with Minkowski functionals providing an additional 11% improvement in \U0001D70E⁡(\U0001D440\U0001D708)
    and 35% in \U0001D70E⁡(Ω\U0001D45A) beyond the extended power spectrum. By contrast,
    moments and wavelet-scattering coefficients provide more limited gains at SO noise
    levels. Our results highlight the potential of non-Gaussian statistics to enhance
    cosmological constraints from SO and future CMB surveys.@eng"
