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…
First steps towards gauge-independent vortex identification through machine learning
Wyatt A. Smith, César Fernández-Ramírez, Jeff Greensite +1
As a first step towards machine identification of confining objects in thermalized lattice gauge configurations, we present our 2dVoId model for center vortex identification on pur…
Finite-volume analysis of the -dibaryon including left-hand-cut effects
Arkaitz Rodas, Lin Qiu, César Fernández-Ramírez +4
We implement the finite-volume representation to study two-baryon interactions from lattice QCD data. We include the left-hand cut induced by one-pion exchange in this formal…
ScatterPrism: convergence for generative simulation and inverse problems in particle and nuclear physics
Zeyu Xia, Tyler Kim, Trevor Reed +3
High-fidelity simulations and complex inverse problems, such as detector modeling and unfolding, are computationally intensive bottlenecks across subatomic physics, yet essential f…
On Dispersive and Nondispersive K-matrix Formalisms
Nils Hüsken, Eric S. Swanson, Adam Szczepaniak
The modeling of coupled-channel effects has become increasingly important due to the availability of highly precise data for a large variety of hadronic (re)scattering processes. T…
Summary of Topical Group on Hadron Spectroscopy (RF07) Rare Processes and Precision Frontier of Snowmass 2021
R. F. Lebed, T. Skwarnicki, L. An +11
Hadron spectroscopy, the driving force of high-energy physics in its early decades, has experienced a renaissance in interest over the past 20 years due to the discovery of scores…
Dispersive approaches for three-particle final states interaction
Peng Guo, I. V. Danilkin, Adam P. Szczepaniak
In this work, we present different representations of Khuri-Treiman equation, the advantage and disadvantage of each representations are discussed. Using a toy model for scattering…
Chiral Extrapolation, Renormalization, and the Viability of the Quark Model
Adam P. Szczepaniak, Eric S. Swanson
The relationship of the quark model to the known chiral properties of QCD is a longstanding problem in the interpretation of low energy QCD. In particular, how can the pion be view…
Heavy Hybrids with Constituent Gluons
E. S. Swanson, A. P. Szczepaniak
Hybrid meson energies are calculated in the static quark limit with the Dynamical Quark Model (DQM). In the DQM, transverse gluons are represented as effective constituents with a…
From Current to Constituent Quarks: a Renormalization Group Improved Hamiltonian-based Description of Hadrons
A. P. Szczepaniak, E. S. Swanson
A model which combines the perturbative behavior of QCD with low energy phenomenology in a unified framework is developed. This is achieved by applying a similarity transformation…
Glueball Spectroscopy in a Relativistic Many-Body Approach to Hadron Structure
Adam Szczepaniak, Eric S. Swanson, Chueng-Ryong Ji +1
A comprehensive, relativistic many-body approach to hadron structure is advanced based on the Coulomb gauge QCD Hamiltonian. Our method incorporates standard many-body techniques w…
Generalized Relativistic Meson Wave Function
A. Szczepaniak, C-R. Ji, S. R. Cotanch
We study the most general, relativistic, constituent meson wave function within a new covariant framework. We find that by including a tensor wave function compone…
