Coulomb gauge approach to scalar hadrons Llanes Estrada, Felipe José Cotanch, Steve General, Ignacio Wang, Ping The Coulomb gauge model, involving an effective QCD Hamiltonian in the Coulomb gauge, is applied to scalar hadrons. Mass predictions are presented for both conventional q ¯ q meson and q ¯ qq ¯ q tetra-quark states. Mixing matrix elements between these states were also computed and diagonalized to provide a reasonable description of the scalar spectrum below 2 GeV. 2023-06-20T13:40:22Z 2023-06-20T13:40:22Z 2023-06-20T13:40:22Z 2008 book part https://hdl.handle.net/20.500.14352/53321 XXXX-XXXX 10.1063/1.2973493 eng AIP Conference Proceedings POCI/FP/81913/2007 DOE DE-FG02- 03ER41260 BSCH-PR34/07-15875 FPA 2004 02602 FPA 2005-02327 HP20060018 open access American Institute of Physics
