Comparison of topological charge definitions in Lattice QCD
Constantia Alexandrou, Andreas Athenodorou, Krzysztof Cichy +5
In this paper, we show a comparison of different definitions of the topological charge on the lattice. We concentrate on one small-volume ensemble with 2 flavours of dynamical, max…
A Lattice Calculation of Parton Distributions
Constantia Alexandrou, Krzysztof Cichy, Kyriakos Hadjiyiannakou +3
We present results for the dependence of the unpolarized, helicity, and transversity isovector quark distributions in the proton using lattice QCD, employing the method of quas…
Testing the Witten-Veneziano Formula on the Lattice
Krzysztof Cichy, Elena Garcia-Ramos, Karl Jansen +2
In this proceeding contribution we report on a test of the famous Witten-Veneziano formula using lattice techniques. We perform dedicated quenched simulations and apply the spectra…
The microscopic Twisted Mass Dirac spectrum and the spectral determination of the LECs of Wilson -PT
Krzysztof Cichy, Elena Garcia-Ramos, K. Splittorff +1
We present the comparison of the analytical microscopic spectral density for lattice QCD with twisted mass fermions with the one obtained on the lattice utilizing con…
Non-perturbative Test of the Witten-Veneziano Formula from Lattice QCD
Krzysztof Cichy, Elena Garcia-Ramos, Karl Jansen +2
We compute both sides of the Witten-Veneziano formula using lattice techniques. For the one side we perform dedicated quenched simulations and use the spectral projector method to…
A Lattice Calculation of Parton Distributions
Constantia Alexandrou, Krzysztof Cichy, Vincent Drach +5
We report on our exploratory study for the direct evaluation of the parton distribution functions from lattice QCD, based on a recently proposed new approach. We present encouragin…
