Spectroscopy From The Lattice: The Scalar Glueball
Ruairà Brett, John Bulava, Daniel Darvish +4
Lattice calculations allow us to probe the low-lying, non-perturbative spectrum of QCD using first principles numerical methods. Here we present the low-lying spectrum in the scala…
Stochastic All-to-All Propagators for Baryon Correlators
John Bulava, Robert Edwards, Colin Morningstar
The effectiveness of various dilution schemes in the evaluation of baryonic two-point functions is compared. The error of a representative set of observables as a function of the n…
Interactions of , and systems at maximal isospin from lattice QCD
Zachary T. Draper, Andrew D. Hanlon, Ben Hörz +3
We study the interactions of systems of two and three nondegenerate mesons composed of pions and kaons at maximal isospin using lattice QCD, specifically , a…
Including Tetraquark Operators in the Low-Lying Scalar Meson Sectors in Lattice QCD
Daniel Darvish, Ruairà Brett, John Bulava +4
Lattice QCD allows us to probe the low-lying hadron spectrum in finite-volume using a basis of single- and multi-hadron interpolating operators. Here we examine the effect of inclu…
From Surface Roughening to QCD String Theory
K. Jimmy Juge, Julius Kuti, Colin Morningstar
Surface critical phenomena and the related onset of Goldstone modes represent fundamental properties of the confining flux in Quantum Chromodynamics. New ideas on surface roughenin…
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…
