The Chiral SU(4)×SU(4) and Scalar Charmed Mesons
並列摘要
It is assumed that the strong-interaction Hamiltonian is broken from the chiral SU(4)×SU(4) symmetry by c0μ0+c1μ8+c2μ15 where the c's are parameters and μ0, μ8, μ15 transforms like component of the (4, 4) ⊕ (4, 4) representation of the chiral SU(4)×SU(4) group. An assumption of asymptoatic symmetry on the scalar and pseudoscalar density is also made. Calculations are made to investigate properties of the scalar charmed mtsons. The mixing problem is also tried.
