This chapter provides an overview of the fundamental framework of scattering theory, which is widely used in particle physics to describe and interpret interactions among elementar…
Exotic Hadron Spectroscopy in Heavy-Flavor Systems
Mikhail Mikhasenko
Recent years have brought a dense sequence of experimental discoveries in heavy-flavor hadron spectroscopy. Heavy-flavor spectroscopy has entered a period in which new hadronic str…
Flow Annealed Importance Sampling Bootstrap meets Differentiable Particle Physics
Annalena Kofler, Vincent Stimper, Mikhail Mikhasenko +2
High-energy physics requires the generation of large numbers of simulated data samples from complex but analytically tractable distributions called matrix elements. Surrogate model…
Wigner rotations for cascade reactions
Kai Habermann, Mikhail Mikhasenko
Parametrization of cascading hadronic reactions is a central tool in hadron spectroscopy for modeling matrix elements and extracting parameters of hadronic states. Implementing the…

Analysis of rescattering effects in final states
Dominik Stamen, Tobias Isken, Bastian Kubis +2
Decays into three particles are often described in terms of two-body resonances and a non-interacting spectator particle. To go beyond this simplest isobar model, crossed-channel r…

We highlight the need for the development of comprehensive amplitude analysis methods to further our understanding of hadron spectroscopy. Reaction amplitudes constrained by first…
Effective-range expansion of the state at the complex threshold
Mikhail Mikhasenko
Evaluation of the effective-range parameters for the state in the LHCb model is examined. The finite width of leads to a shift of the expansion point into the comp…
