Exploring the pi+ pi+ interaction in lattice QCD
H. R. Fiebig, K. Rabitsch, H. Markum +1
An effective residual interaction for a meson-meson system is computed in lattice QCD. We describe the theoretical framework and present its application to the I=2 channel S-wave i…
On the I=2 channel pi-pi interaction in the chiral limit
H. R. Fiebig, H. Markum, A. Mihaly +1
An approximate local potential for the residual pi+ pi+ interaction is computed. We use an O(a**2) improved action on a coarse 9x9x9x13 lattice with approximately a=0.4fm. The resu…
Two-body spectra of pseudoscalar mesons with an --improved lattice action using Wilson fermions
H. R. Fiebig, H. Markum, A. Mihaly +2
We extend our calculations with the second-order tree-level and tadpole improved next-nearest-neighbor action to meson-meson systems. Correlation matrices built from interpolating…
Potentials between heavy-light mesons from lattice and inverse scattering theory
H. R. Fiebig, H. Markum, A. Mihaly +1
We extend our investigation of heavy-light meson-meson interactions to a system consisting of a heavy-light meson and the corresponding antiparticle. An effective potential is obta…
Forces between composite particles in QCD
H. R. Fiebig, A. Mihaly, H. Markum +1
Starting from the meson-meson Green function in 3+1 dimensional quenched lattice QCD we calculate potentials between heavy-light mesons for various light-quark mass parameters. For…
