Phenomenology of Relativistic Reaction Amplitudes within the Isobar Approximation
JPAC Collaboration, A. Jackura, C. Fernández-Ramírez +7
Further progress in hadron spectroscopy necessitates the phenomenological description of three particle reactions. We consider the isobar approximation, where the connected part of…
Determination of the pole position of the lightest hybrid meson candidate
JPAC Collaboration, A. Rodas, A. Pilloni +9
Mapping states with explicit gluonic degrees of freedom in the light sector is a challenge, and has led to controversies in the past. In particular, the experiments have reported t…
Pole position of the from -decay
JPAC Collaboration, M. Mikhasenko, A. Pilloni +8
We perform an analysis of the three-pion system with quantum numbers produced in the weak decay of leptons. The interaction is known to be dominated by the axia…
Regge phenomenology of the and poles
JPAC collaboration, J. A. Silva-Castro, C. Fernandez-Ramirez +8
We use Regge phenomenology to study the structure of the poles of the and spectrum. We employ the available pole extractions from partial wave analysis of meson scatter…
What is the right formalism to search for resonances? II. The pentaquark chain
JPAC Collaboration, A. Pilloni, J. Nys +8
We discuss the differences between several partial-wave analysis formalisms used in the construction of three-body decay amplitudes involving fermions. Specifically, we consider th…
Khuri-Treiman equations for scattering
JPAC Collaboration, M. Albaladejo, N. Sherrill +7
The Khuri-Treiman formalism models the partial-wave expansion of a scattering amplitude as a sum of three individual truncated series, capturing the low-energy dynamics of the dire…
