What is the right formalism to search for resonances?

JPAC Collaboration, M. Mikhasenko, A. Pilloni +8

Hadron decay chains constitute one of the main sources of information on the QCD spectrum. We discuss the differences between several partial wave analysis formalisms used in the l…

Analyticity Constraints for Hadron Amplitudes: Going High to Heal Low Energy Issues

JPAC Collaboration, V. Mathieu, J. Nys +7

Analyticity constitutes a rigid constraint on hadron scattering amplitudes. This property is used to relate models in different energy regimes. Using meson photoproduction as a ben…

New analysis of $η π$ tensor resonances measured at the COMPASS experiment

A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232

We present a new amplitude analysis of the $η π$ $D$ -wave in $π^{-} p \to η π^{-} p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$ -mat…

Dalitz plot analyses of $J / ψ \to π^{+} π^{-} π^{0}$ , $J / ψ \to K^{+} K^{-} π^{0}$ , and $J / ψ \to K_{S}^{0} K^{\pm} π^{\mp}$ produced via $e^{+} e^{-}$ annihilation with initial-state radiation

The BaBar Collaboration

We study the processes $e^{+} e^{-} \to γ_{ISR} J / ψ$ where $J / ψ \to π^{+} π^{-} π^{0}$ , $J / ψ \to K^{+} K^{-} π^{0}$ , and $J / ψ \to K_{S}^{0} K^{\pm} π^{\mp}$ using a data sample of 519 $f b^{- 1}$ rec…
