We study twoand 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 are able to determine hundreds of twoand three-particle energy levels, in nine different momentum frames, with high precision. We fit these levels using the relativistic finite-volume formalism based on a generic effective field theory in order to determine the parameters of the twoand three-particle K-matrices. We find… Expand


Scattering of two and three physical pions at maximal isospin from lattice QCD
We present the first direct $N_f=2$ lattice QCD computation of two- and three-$\pi^+$ scattering quantities that includes an ensemble at the physical point. We study the quark mass dependence of theExpand
A cross-channel study of pion scattering from lattice QCD
We use a chiral model for pion interactions, in the inverse amplitude formalism, to perform a simultaneous analysis of lattice QCD results for pion-pion scattering in all three isospin channels. TheExpand
Two-nucleon S -wave interactions at the SU(3) flavor-symmetric point with mud≈msphys : A first lattice QCD calculation with the stochastic Laplacian Heaviside method
We report on the first application of the stochastic Laplacian Heaviside method for computing multiparticle interactions with lattice QCD to the two-nucleon system. Like the Laplacian HeavisideExpand
I=2 ππ S-wave scattering phase shift from lattice QCD
The π+π+ s-wave scattering phase-shift is determined below the inelastic threshold using Lattice QCD. Calculations were performed at a pion mass of mπ ≈ 390 MeV with an anisotropic nf = 2+1 cloverExpand
Two meson systems with Ginsparg-Wilson valence quarks
Unphysical effects associated with finite lattice spacing and partial quenching may lead to the presence of unphysical terms in chiral extrapolation formulas. These unphysical terms must then beExpand
Leading hadronic contribution to (g−2)μ from lattice QCD with Nf=2+1 flavors of O(a) improved Wilson quarks
The comparison of the theoretical and experimental determinations of the anomalous magnetic moment of the muon $(g-2)_\mu$ constitutes one of the strongest tests of the Standard Model at lowExpand
Two- and Three-Pion Finite-Volume Spectra at Maximal Isospin from Lattice QCD.
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 irreducibleExpand
Lattice QCD and Three-particle Decays of Resonances
Most strong-interaction resonances have decay channels involving three or more particles, including many of the recently discovered $X$, $Y$ and $Z$ resonances. In order to study such resonances fromExpand
Lattice QCD study of the s-wave $\pi\pi $ scattering lengths in the I=0 and 2 channels
The s-wave pion-pion (ππ) scattering lengths are computed below the inelastic threshold by the Luscher technique with pion masses ranging from 240 to 463 MeV. In the Asqtad-improved staggered fermionExpand
Pion scattering in the isospin $I=2$ channel from elongated lattices
Pion-pion elastic scattering in the isospin I=2 channel is investigated in two-flavor dynamical lattice QCD. Six ensembles are used with lattices elongated in one of the spatial dimensions at twoExpand
