Title: Pole Position of the a1(1260) with a three-body unitary framework from the infinite and finite volume

Abstract: Masses, widths, and branching ratios of hadronic resonances are quantified by their pole positions and residues with respect to transition amplitudes on the Riemann sheets of the complex energy-plane. We calculate three-body scattering amplitudes with integration contours that respect the analytic structure in the physical energy region. Using these amplitudes we determine the pole position of the a1(1260) resonance with both the infinite and finite volume by fitting to data from the ALEPH experiment and Lattice QCD data respectively.
