Interactions of two and three mesons including higher partial waves from lattice QCD
Tyler D. Blanton, Andrew D. Hanlon, Ben Hörz +3
We study two- and three-meson systems composed either of pions or kaons at maximal isospin using Monte Carlo simulations of lattice QCD. Utilizing the stochastic LapH method, we ar…
Two-nucleon S-wave interactions at the flavor-symmetric point with : a first lattice QCD calculation with the stochastic Laplacian Heaviside method
Ben Hörz, Dean Howarth, Enrico Rinaldi +11
We report on the first application of the stochastic Laplacian Heaviside method for computing multi-particle interactions with lattice QCD to the two-nucleon system. Like the Lapla…
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…
Two- and three-pion finite-volume spectra at maximal isospin from lattice QCD
Ben Hörz, Andrew Hanlon
We present the three-pion spectrum with maximal isospin in a finite volume determined from lattice QCD, including excited states in addition to the ground states across various irr…
The dibaryon from lattice QCD with SU(3) flavor symmetry
Andrew Hanlon, Anthony Francis, Jeremy Green +2
We show recent results from the Mainz group using CLS ensembles generated at the symmetric point. Temporal correlation functions using two-baryon interpolatin…
