The in a Unitary Coupled-Channel Three-Body Approach
Ajay S. Sakthivasan, Yuchuan Feng, Michael Döring +1
The paper develops a unitary three‑body coupled‑channel model that incorporates triangle‑singularity effects to describe the narrow enhancement near 1.42 GeV observed in COMPASS da…
Coupled-channel approach to isotensor scattering from lattice QCD
Yuchuan Feng, Chris Culver, Michael Döring +3
The quest to understand three-body dynamics from first-principle QCD includes the study of non-resonant and resonant systems. The isospin system is of particular interest hav…
Dynamical coupled-channel models for hadron dynamics
Michael Döring, Johann Haidenbauer, Maxim Mai +1
Dynamical coupled-channel (DCC) approaches parametrize the interactions and dynamics of two and more hadrons and their response to different electroweak probes. The inclusion of un…
Effects of Final State Interactions on Landau Singularities
Ajay S. Sakthivasan, Maxim Mai, Akaki Rusetsky +1
In certain kinematic and particle mass configurations, triangle singularities may lead to line-shapes which mimic the effects of resonances. This well-known effect is scrutinized h…
