Study on the mechanism of open-flavor strong decays

  • Open-flavor strong decays are studied based on the interaction of a potential quark model. The decay process is related to the s-channel contribution of the same scalar confinement and one-gluon-exchange (OGE) interaction in the quark model. After we adopt the prescription of massive gluons in a time-like region from the lattice calculation, the approximation of four-fermion interaction is applied. The numerical calculation is performed to the meson decays in u, d and s light flavor sectors. The analysis of the D/S ratios of b1ωπ and a1ρπ shows that the scalar interaction should be dominant in the open-flavor decays.

Study on the mechanism of open-flavor strong decays

    Corresponding author: DENG Wei-Zhen,

Abstract: Open-flavor strong decays are studied based on the interaction of a potential quark model. The decay process is related to the s-channel contribution of the same scalar confinement and one-gluon-exchange (OGE) interaction in the quark model. After we adopt the prescription of massive gluons in a time-like region from the lattice calculation, the approximation of four-fermion interaction is applied. The numerical calculation is performed to the meson decays in u, d and s light flavor sectors. The analysis of the D/S ratios of b1ωπ and a1ρπ shows that the scalar interaction should be dominant in the open-flavor decays.
