11:00 → 12:00 Damavand: A Neural-Network Framework for Diffractive QCD Analyses

In this talk, I will introduce Damavand, a neural-network-based QCD analysis framework developed for the determination of diffractive parton distribution functions (diffractive PDFs). Building upon the MontBlanc framework, Damavand combines perturbative QCD calculations at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) with DGLAP evolution, flexible neural-network parametrizations, and Monte Carlo replica methods for uncertainty estimation.
As its first application, Damavand has been employed to extract the MAP-diff-PDF1.0 distributions from HERA diffractive deep-inelastic scattering measurements within the fracture-function formalism. I will discuss the main features of the framework, its computational methodology, and selected phenomenological results, including comparisons with existing diffractive PDF determinations. Finally, I will briefly outline possible extensions and future
