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…

Tensor Resonance in $J / I ¨ J / I ¨ $ Scattering from Lattice QCD

Geng Li, Chunjiang Shi, Ying Chen +1

The $S$ -wave scattering amplitudes of $J / I ¨ J / I ¨ $ with quantum numbers $J^{P C} = 0^{++}$ and $2^{++}$ are determined up to 6600\,MeV using lattice QCD calculations at $m_Ï\approx 4…

$η_{c} η_{c}$ 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, $I ¨ _{1}$ and $I^\cdot_{1}$ , in $N_{f} = 2$ lattice QCD at a pion mass $m_{I ¨} \approx 417 MeV$ . The…

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…
