Pole position of the resonance in a three-body unitary framework
Daniel Sadasivan, Andrei Alexandru, Hakan Akdag +6
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 c…
Coupled-channel analysis of pion- and eta-electroproduction with the Jülich-Bonn-Washington model
Maxim Mai, Michael Döring, Carlos Granados +6
Pion and eta electroproduction data are jointly analyzed for the first time, up to a center-of-mass energy of 1.6 GeV. The framework is a dynamical coupled-channel model, based on…
Three-body dynamics of the resonance from lattice QCD
Maxim Mai, Andrei Alexandru, Ruairí Brett +4
Resonant hadronic systems often exhibit a complicated decay pattern in which three-body dynamics play a relevant or even dominant role. In this work we focus on the res…
Jülich-Bonn-Washington Model for Pion Electroproduction Multipoles
Maxim Mai, Michael Döring, Carlos Granados +5
Pion electroproduction off the proton is analyzed in a new framework based on a general parametrization of transition amplitudes, including constraints from gauge invariance and th…
Multi-particle systems on the lattice and chiral extrapolations: a brief review
Maxim Mai, Michael Döring, Akaki Rusetsky
The extraction of two- and three-body hadronic scattering amplitudes and the properties of the low-lying hadronic resonances from the finite-volume energy levels in lattice QCD rep…
Three-body interactions from the finite-volume QCD spectrum
Ruairí Brett, Chris Culver, Maxim Mai +3
We perform a fit of the finite-volume QCD spectrum of three pions at maximal isospin to constrain the three-body force. We use the unitarity-based relativistic three-particle quant…
