Variational Neural Network Approach to QFT in the Field Basis
Kevin Braga, Nobuo Sato, Adam P. Szczepaniak
We present a variational neural network approach for solving quantum field theories in the field basis, focusing on the free Klein-Gordon model formulated in momentum space. While…
New insights into the doubly charmed exotic mesons
Di Guo, Qin-He Yang, Ling-Yun Dai +1
Using effective Lagrangians constrained by the heavy quark spin symmetry and chiral symmetry, for the light quarks, we analyze the , and $D^0\bar{D}…
Finite-volume quantization condition from the representation
Sebastian M. Dawid, Andrew W. Jackura, Adam P. Szczepaniak
We propose a new model-independent method for determining hadronic resonances from lattice QCD. The formalism is derived from the general principles of unitarity and analyticity, a…
Towards a unified description of hadron scattering at all energies
Dominik Stamen, Daniel Winney, Arkaitz Rodas +5
The construction of general amplitudes satisfying symmetries and -matrix constraints has been the primary tool in studying the spectrum of hadrons for over half a century. In th…
A unitary coupled-channel three-body amplitude with pions and kaons
Yuchuan Feng, Fernando Gil, Michael Döring +4
Three-body dynamics above threshold is required for the reliable extraction of many amplitudes and resonances from experiment and lattice QCD. The S-matrix principle of unitarity c…
Coulomb confinement in the Hamiltonian limit
Sebastian M. Dawid, Wyatt A. Smith, Arkaitz Rodas +4
The Gribov--Zwanziger scenario attributes the phenomenon of confinement to the instantaneous interaction term in the QCD Hamiltonian in the Coulomb gauge. For a static quark-antiqu…
