“…Using the model from Ref. [23], we estimate that the yields of events having at least one of the pions in the FT acceptance is one order of magnitude smaller than the single π 0 events, and can be safely neglected.…”

Current and future experiments at the high intensity frontier are expected to produce an enormous amount of data that needs to be collected and stored for offline analysis. Thanks to the continuous progress in computing and networking technology, it is now possible to replace the standard 'triggered' data acquisition systems with a new, simplified and outperforming scheme. 'Streaming readout' (SRO) DAQ aims to replace the hardware-based trigger with a much more powerful and flexible software-based one, that considers the whole detector information for efficient real-time data tagging and selection. Considering the crucial role of DAQ in an experiment, validation with on-field tests is required to demonstrate SRO performance. In this paper we report results of the on-beam validation of the Jefferson Lab SRO framework. We exposed different detectors (PbWO-based electromagnetic calorimeters and a plastic scintillator hodoscope) to the Hall-D electronpositron secondary beam and to the Hall-B production electron beam, with increasingly complex experimental conditions. By comparing the data collected with the SRO system against the traditional DAQ, we demonstrate that the SRO performs as expected. Furthermore, we provide evidence of its superiority in implementing sophisticated AI-supported algorithms for real-time data analysis and reconstruction.

“…Amplitudes describing the polarization and ηπ decay angles for L m = S ± 0 , D ± 0 , D ± 1 , D + 2 and D − −1 are utilized in the fit following the model described in Ref. [216]. Figure 14 shows preliminary results for the measured intensity of the dominant waves, with evidence for tensor meson a 2 (1320) production in the D + 2 wave in ηπ 0 produced through natural parity (vector) exchange and the D − 1 wave in ηπ − through unnatural parity (pion) exchange.…”

We summarize the ongoing scientific program of the 12 GeV Continuous Electron Beam Accelerator Facility (CE-BAF) and give an outlook into future scientific opportunities. The program addresses important topics in nuclear, hadronic, and electroweak physics including nuclear femtography, meson and baryon spectroscopy, quarks and gluons in nuclei, precision tests of the standard model, and dark sector searches. Potential upgrades of CEBAF are considered, such as higher luminosity, polarized and unpolarized positron beams, and doubling the beam energy.

“…In Ref. [545] we revised this hypothesis and introduced the NSWSZ only in the ω production, so that the dip at t = −0.5 GeV 2 is filled by a nonvanishing ρ contribution. In this model, the ρ amplitude does not feature the NSWZ and lead to a nondipping shape of the f 2 differential cross section, in agreement with the recent measurements by the CLAS collaboration [555,556].…”

The last two decades have witnessed the discovery of a myriad of new and unexpected hadrons. The future holds more surprises for us, thanks to new-generation experiments. Understanding the signals and determining the properties of the states requires a parallel theoretical effort. To make full use of available and forthcoming data, a careful amplitude modeling is required, together with a sound treatment of the statistical uncertainties, and a systematic survey of the model dependencies. We review the contributions made by the Joint Physics Analysis Center to the field of hadron spectroscopy.
