Low and high spin mesons from Clover-Wilson lattices
arXiv:0903.2358 · doi:10.1103/PhysRevD.79.114503
Abstract
We present results for excited meson spectra from clover-Wilson configurations provided by the CP-PACS Collaboration. In our study we investigate both low and high spin mesons. For spin-0 and spin-1 mesons, we are especially interested in the excited states. To access these states we construct several different interpolators from quark sources of different spatial smearings and calculate a matrix of correlators. For this matrix we then solve a generalized eigenvalue problem. For spin-2 and spin-3, we extract only the lowest lying states.
