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 phase shift determinations from a two-scalar field theory
Daniel Darvish, Ruairí Brett, John Bulava +3
A field theory involving two interacting scalar fields, previously studied by Rummukainen and Gottlieb, is revisited. Our study is not restricted to the limit of large quartic coup…
