Multi-Pion Systems in Lattice QCD and the Three-Pion Interaction
Silas R. Beane, William Detmold, Thomas C. Luu +3
The ground-state energies of 2, 3, 4 and 5 π^+'s in a spatial volume V (2.5 fm)^3 are computed with lattice QCD. By eliminating the leading contribution from three-π^+ interactions…
The K+K+ Scattering Length from Lattice QCD
Silas Beane, Thomas Luu, Kostas Orginos +4
The K+K+ scattering length is calculated in fully-dynamical lattice QCD with domain-wall valence quarks on the MILC asqtad-improved gauge configurations with rooted staggered sea q…
n-Boson Energies at Finite Volume and Three-Boson Interactions
Silas R. Beane, William Detmold, Martin J. Savage
We calculate the volume dependence of the ground-state energy of n identical bosons with short-range repulsive interactions in a periodic spatial volume of side L, up to and includ…
Precise Determination of the I=2 pipi Scattering Length from Mixed-Action Lattice QCD
Silas R. Beane, Thomas C. Luu, Kostas Orginos +4
The I=2 pipi scattering length is calculated in fully-dynamical lattice QCD with domain-wall valence quarks on the asqtad-improved coarse MILC configurations (with fourth-rooted st…
BB Potentials in Quenched Lattice QCD
William Detmold, Kostas Orginos, Martin J. Savage
The potentials between two B-mesons are computed in the heavy-quark limit using quenched lattice QCD at . Non-zero central potentials are clearly evident in…
