Scalar and tensor structures in $J / ψ J / ψ$ scattering from lattice QCD

Geng Li, Chunjiang Shi, Ying Chen +1

The $^{1} S_{0}$ and $^{5} S_{2}$ amplitudes of $J / ψ J / ψ$ scattering are determined up to 6.6~GeV from $N_{f} = 2$ lattice QCD simulations at $m_{π} \approx 420$ ~MeV and $250$ ~MeV. We observe an at…

$η_{c} η_{c}$ and $J / ψ J / ψ$ scatterings from lattice QCD

Geng Li, Chunjiang Shi, Ying Chen +1

We investigate the $S$ -wave $η_{c} η_{c}$ and $J / ψ J / ψ$ scattering in the $J^{P C} = (0, 2)^{++}$ channels up to a center-of-mass energy of 6.6~GeV. The calculations are carried out at two u…

Decay properties of light $1^{-+}$ hybrids

Juzheng Liang, Siyang Chen, Ying Chen +2

We explore the decay properties of the isovector and isoscalar $1^{-+}$ light hybrids, $π_{1}$ and $η_{1}$ , in $N_{f} = 2$ lattice QCD at a pion mass $m_{π} \approx 417 MeV$ . The McN…

Form factor for Dalitz decays from $J / ψ$ to light pseudoscalars

Chunjiang Shi, Ying Chen, Xiangyu Jiang +3

We calculate the form factor $M (q^{2})$ for the Dalitz decay $J / ψ \to γ^{*} (q^{2}) η_{(N_{f} = 1)}$ with $η_{(N_{f})}$ being the SU( $N_{f}$ ) flavor singlet pseudoscalar meson. The difference among…

$X (3872)$ Relevant $D D ˉ^{*}$ Scattering in $N_{f} = 2$ Lattice QCD

Haozheng Li, Chunjiang Shi, Ying Chen +4

We study the $S$ -wave $D D ˉ^{*} (I = 0)$ scattering at four different pion masses $m_{π}$ ranging from 250 MeV to 417 MeV from $N_{f} = 2$ lattice QCD. Three energy levels $E_{2, 3, 4}$ are…
