$S - P - D$ Mixing in Vector Quarkonia from the Salpeter Equation with Optimized Wave Function Representations

Wen-Yuan Ke, Qiang Li, Tianhong Wang +2

This paper proposes a novel mechanism based on the instantaneous Bethe-Salpeter (Salpeter) equation for investigating wave function mixing in vector mesons such as $ψ (3770)$ . Conve…

$η_{c 2} (^{1} D_{2})$ and its electromagnetic decays

Xin-Yao Du, Su-Yan Pe, Wei Li +5

The spin-singlet state $η_{c 2} (^{1} D_{2})$ has not been discovered in experiment and it is the only missing low-excited $D$ -wave charmonium, so in this paper, we like to study its prop…

Strong decays of $P_{ψ}^{N} (4312)^{+}$ to $J / ψ (η_{c}) p$ and $D ˉ^{(*)} Λ_{c}$ within the Bethe-Salpeter framework

Qiang Li, Chao-Hsi Chang, Tianhong Wang +1

Based on the effective Lagrangian in the heavy quark limit, we calculate the one-boson-exchange interaction kernel of $P_{ψ}^{N} (4312)^{+}$ as the $D ˉ Σ_{c}$ molecular state in isospin-…
