A Quasi-staggered Scheme on Lattice
Daqing Liu
Utilizing a picture of string and string spinors, we show a simpler version of staggered action. The advantage of this action is that in this action there always exist pair of quar…
Independent Operators at Different Dimension
Yin Chen, Daqing Liu, Yubin Liu +1
To apply lattice QCD in the calculation of glueball spectrum it is needed firstly to know associated operators acting on vacuum. We show how to find all the independent representat…
Charmonium Spectrum from Quenched Lattice QCD with Tadpole Improvement Action
Da Qing Liu
We report here our lattice simulation on the charmonium spectra in the quenched approximation. Because the full adjustment on the nonperturbative parameters such as , , $…
The First Calculation for the Mass of the Ground Glueball State on Lattice
Da Qing Liu, Ji Min Wu
Under the quenched approximation, we perform a lattice calculation for the mass of the ground glueball state in channel on a lattice. Our calculation show…
The Calculation of the Perturbative Expansion of Wilson Loops on Lattice
Da Qing Liu, Ji Min Wu
We introduce an approach to expand gauge-invariant Wilson operators on lattice. This approach is based on non-abelian Stokes theorem and overcomes some shortage of some former meth…
The Combination of Wilson Loops into Operators in Lattice Pure Gauge Theory
Da Qing Liu, Ji Ming Wu, Ying Chen
To calculate the mass of glueballs with quantum number in lattice gauge theory by using Wilson loops, we discuss their combinations of Wilson loops into irreducible repres…
