Challenges of Lattice Calculation of Scalar Mesons
arXiv:0805.3364 · doi:10.1063/1.2973517
Abstract
I review a proposed pattern of the light scalar mesons with q\bar{q} mesons and glueball above 1 GeV and tetraquark mesoniums below 1 GeV. Several challenges and caveats of calculating these light scalar mesons with dynamical fermions are discussed.
