I=3/2 nucleon-pion scattering and the Delta(1232) resonance on 2+1 flavor CLS ensembles using the stochastic LapH method
Christian Walther Andersen, John Bulava, Ben Hörz +1
Calculations of the elastic nucleon-pion scattering phase shifts on two lattice QCD ensembles with and are presented. The en…
Meson-Nucleon Scattering Amplitudes from Lattice QCD
John Bulava
Lattice QCD calculations of resonant meson-meson scattering amplitudes have improved significantly due to algorithmic and computational advances. However, progress in meson-nucleon…
Including Tetraquark Operators in the Low-Lying Scalar Meson Sectors in Lattice QCD
Daniel Darvish, Ruairí 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…
Spectroscopy From The Lattice: The Scalar Glueball
Ruairí 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…
Scattering amplitudes from finite-volume spectral functions
John Bulava, Maxwell T. Hansen
A novel proposal is outlined to determine scattering amplitudes from finite-volume spectral functions. The method requires extracting smeared spectral functions from finite-volume…
String breaking by light and strange quarks in QCD
John Bulava, Ben Hörz, Francesco Knechtli +4
The energy spectrum of a system containing a static quark anti-quark pair is computed for a wide range of source separations using lattice QCD with dynamical fla…
