Scalar glueball- $s s ˉ$ mixing in one flavor lattice QCD

Long-Cheng Gui, Wei Sun, Ying Chen +3

We investigate the mixing between the lowest-lying scalar glueball and the $s s$ meson in $N_{f} = 1$ lattice quantum chromodynamics (QCD) utilizing an anisotropic $16^3 \tim…

Production Rate of Glueball-like $X (2370)$ in $J / ψ$ Radiative Decay

Ying Chen, Long-Cheng Gui, Geng Li +1

$X (2370)$ falls in the mass region of the lowest pseudoscalar glueball predicted by lattice QCD studies and its decay properties are similar to those of $η_{c}$ . A previous lattice Q…

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…

Portraits of Charmoniumlike States

Qingyang Liu, Xiangyu Jiang, Ying Chen +2

The charm quark density-density correlation is calculated for $1 S$ and $1 P$ conventional charmonia and $J^{P C} = 1^{-+}, 0^{+-}$ charmoniumlike states from lattice QCD and are interpr…

Use QUDA for lattice QCD calculation with Python

Xiangyu Jiang, Chunjiang Shi, Ying Chen +2

We developed PyQUDA, a Python wrapper for QUDA written in Cython, designed to facilitate lattice QCD calculations using the Python programming language. PyQUDA leverages the optimi…

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…

Charm physics with overlap fermions on 2+1-flavor domain wall fermion configurations

Donghao Li, Ying Chen, Ming Gong +3

Decay constants of pseudoscalar mesons $D$ , $D_{s}$ , $η_{c}$ and vector mesons $D^{*}$ , $D_{s}^{*}$ , $J / ψ$ are determined from $N_{f} = 2 + 1$ lattice QCD at a lattice spacing $a \sim 0.08$ fm. For…

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…

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…

Radiative transition decay width of $ψ_{2} (3823) \to γ χ_{c 1}$ from lattice QCD

Ning Li, Yan Gao, Feiyu Chen +4

We present an exploratory $N_{f} = 2$ lattice QCD study of $ψ_{2} (3823) \to γ χ_{c 1}$ at a pion mass $m_{π} \approx 350$ ~MeV. The related two-point and three-piont functions are calculated us…
