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…
Form factors of the meson from effective field theory and the lattice
Ulf-G. MeiÃner, Akaki Rusetsky, Ajay S. Sakthivasan +2
The calculation of resonance form factors in effective field theory as well as on the lattice is a highly challenging task. In a recent paper, we proposed a novel method based on t…
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…
