Determining universal spectra from probability distributions
Charles Kacir, Joseph Moscoso, Amy Nicholson +2
The probability distribution of a two-particle correlation function computed over background auxiliary field configurations, used to generate the interactions, has been shown to in…
Resolving the structure of bound states using lattice quantum field theories
Joseph Moscoso, Felipe G. Ortega-Gama, Raúl A. Briceño +3
This work presents the first lattice calculation of a two-to-two particle matrix element of a local current. This exploratory calculation is performed using a leading-order pionles…
Di-nucleons do not form bound states at heavy pion mass
John Bulava, M. A. Clark, Arjun S. Gambhir +16
We perform a high-statistics lattice QCD calculation of the low-energy two-nucleon scattering amplitudes. In order to address discrepancies in the literature, the calculation is pe…
The from Lattice QCD: Determining the Finite-volume Spectra
John Bulava, Bárbara Cid-Mora, Andrew D. Hanlon +8
This work presents technical details of determining the finite-volume energy spectra for the scattering amplitude of the coupled-channel from lattice QCD data. The i…
Low-lying baryon resonances from lattice QCD
John Bulava, Barbara Cid-Mora, Andrew D. Hanlon +8
Recent results studying the masses and widths of low-lying baryon resonances in lattice QCD are presented. The -wave scattering lengths for both total isospins an…
