S-matrix informed neural networks for amplitude analysis
Wyatt A. Smith, Arkaitz Rodas, Marius D. Thomas +5
Reconstructing scattering amplitudes from finite, noisy, and mutually inconsistent measurements is an ill-posed inverse problem common to many reactions relevant to particle physic…
Neuro-dispersive extractions of light-meson resonances
Wyatt A. Smith, Arkaitz Rodas, Marius D. Thomas +5
We present the first dispersive extraction of resonant poles from analytically continued neural networks. We use S-matrix informed neural networks (SINNs) trained to respect unitar…
Unraveling weak radiative hyperon decays with broken flavor symmetry
Kaiwen Chen, Lin Qiu, Jin Sun +2
We present a broken flavor analysis of weak radiative decays of spin-1/2 hyperons, incorporating current-current and electromagnetic-penguin contributions as well as charge…
Production Effects and Final-state Interactions in
D. Winney, S. Gonzàlez-Solís, M. Mikhasenko +8
We investigate the signal channel of in the -wave. This channel has recently been analyzed by the COMPASS collaboration using t…
photoproduction near threshold and signals for the hidden charm pentaquarks
Ming-Xiao Duan, Chang Gong, Lin Qiu +1
We study the photoproduction near threshold to investigate the role played by the open charm channels and possible signals from the hidden charm pentaquark…
