Study of the heavy molecular states in the quark model with meson exchange interaction

  • Some charmonium-like resonances such as X(3872) can be interpreted as possible D(*)D(*) molecular states. Within the quark model, we study the structure of such molecular states and the similar B(*)D(*) molecular states by taking into account the light meson exchange (π, η, ρ, ω and σ) between two light quarks from different mesons.

Study of the heavy molecular states in the quark model with meson exchange interaction

    Corresponding author: DENG Wei-Zhen,

Abstract: Some charmonium-like resonances such as X(3872) can be interpreted as possible D(*)D(*) molecular states. Within the quark model, we study the structure of such molecular states and the similar B(*)D(*) molecular states by taking into account the light meson exchange (π, η, ρ, ω and σ) between two light quarks from different mesons.
