Titel: Bayesian Analysis and Analytic Continuation of Scattering
Amplitudes from Lattice QCD<br>
</p>
Abstract: We present a novel procedure for analyzing the
lattice-QCD spectrum via the finite-volume formalism to obtain
constraints on multi-hadron scattering amplitudes at both real and
complex energies. This approach combines a Bayesian reconstruction
of the scattering amplitude on the real axis with Nevanlinna
interpolation for analytic continuation to complex-valued
energies. The method is non-parametric, inherently accounting for
parametrization dependence within the uncertainty. We demonstrate
the applicability of this approach using real lattice-QCD data in
resonant systems from the HadSpec and BaSc collaborations.<br>
