Heavy-meson light-cone distribution amplitudes are essential nonperturbative inputs for precision heavy-flavor phenomenology. We present a first-principles lattice-QCD determination of heavy-meson LCDAs in both QCD and HQET using the HQLaMET framework. Simulations on multiple ensembles enable controlled continuum, chiral, and infinite-momentum extrapolations. Improved lattice techniques...

The high-momentum components and associated off-shell effects arising from nucleon-nucleon short-range correlations (SRCs) are important features of nuclear structure beyond the mean-field approximation. Existing studies have primarily relied on electron scattering, while the sensitivity of meson scattering to SRCs requires further investigation in specific reactions. In this report, we...

Light-cone distribution amplitudes (LCDAs) are essential to precision phenomenology in heavy baryon decays. In this work, we derive a factorization formula connecting the leading-twist QCD LCDA to the boosted HQET LCDA of the $\Lambda_b$ baryon in the peak region. We demonstrate a significant simplification of the matching procedure by applying the method-of-regions to perturbative...

Femtoscopy provides a unique laboratory for studying hadron-hadron interactions via two-particle correlation functions (CFs), yet its predictive power is fundamentally limited by the unknown emission source $\mathcal{S}(r)$. We present a model-independent reconstruction of the proton-proton source by formulating the Koonin-Pratt equation as an inverse problem, stabilized through Tikhonov...
