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…
Contribution of constituent quark model states to the dynamics of the and resonances
M. Albaladejo, P. Fernandez-Soler, J. Nieves +1
The masses of the and resonances lie below the and thresholds respectively, which contradicts the predictions of naive quark mode…
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…
Heavy-to-light scalar form factors from Muskhelishvili-Omnès dispersion relations
De-Liang Yao, P. Fernandez-Soler, M. Albaladejo +2
By solving the Muskhelishvili-Omnès integral equations, the scalar form factors of the semileptonic heavy meson decays , , $\b…
