(ECT, Trento ; INFN, Genoa ; Fond. Bruno Kessler, Trento) ; Ketzer, B. (Bonn U., HISKP) ; Szczepaniak, A.P. (Indiana U., CEEM ; Indiana U. ; Jefferson Lab)
We discuss unitarity constraints on the dynamics of a system of three interacting particles. We show how the short-range interaction that describes three-body resonances can be separated from the long-range exchange processes, in particular the one-pion-exchange process. [...]

/JPAC Collaboration
In light of recent experimental results, we revisit the dispersive analysis of the $\omega \to 3\pi$ decay amplitude and of the $\omega\pi^0$ transition form factor. Within the framework of the Khuri-Treiman equations, we show that the $\omega \to 3\pi$ Dalitz-plot parameters obtained with a once-subtracted amplitude are in agreement with the latest experimental determination by BESIII.

Paris-Saclay) et al.
The RD51 collaboration developed the Scalable Readout System (SRS) as part of its R&D; activities on Micro-Pattern Gaseous Detectors. This common multi-purpose readout system allows to read out small R&D; detectors (0.2k channels) up to mid-sized experiments with multiple detectors (2.5k to 5k channels). [...]

$\pi^-p\to\eta^{(\prime)}\, \pi^- p$ in the double-Regge region

/JPAC Collaboration
The production of $\eta^{(\prime)}\pi$ pairs constitutes one of the golden channels to search for hybrid exotics, with explicit gluonic degrees of freedom. Understanding the dynamics and backgrounds associated to $\eta^{(\prime)}\pi$ production above the resonance region is required to impose additional constraints to the resonance extraction. [...]

New analysis of $\eta\pi$ tensor resonances measured at the COMPASS experiment
/ JPAC Collaboration
We present a new amplitude analysis of the $\eta\pi$ $D$-wave in $\pi^- p\to \eta\pi^- p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$-matrix, we find two resonances that can be identified with the $a_2(1320)$ and the excited $a_2^\prime(1700)$, and perform a comprehensive analysis of their pole positions.
