چکیده
We study the location of the partition function zeros in the complex β plane (Fisher’s Zeros) for SU(2) lattice gauge theory on L4 lattices. We discuss recent attempts to locate complex zeros for L = 4 and 6. We compare results obtained using various polynomial approximations of the logarithm of the density of states and a straightforward MC reweighting. We conclude that the method based on a combination of discrete Chebyshev orthogonality and patching plaquette distributions at different β provides the more reliable estimates.

We compare MC calculations of the density of states in SU(2) pure gauge theory with the weak and strong coupling expansions. Surprisingly, the range of validity of the two approximations overlap significantly, however the large order behavior of both expansions appear to be similar to the corresponding expansions of the plaquette. We discuss the implications for the calculation of the Fisher’s ...

The substantial progress that has been achieved in lattice QCD in the last years is pointed out. I compare the simulation cost and systematic effects of several lattice QCD formulations and discuss a number of topics such as lattice spacing scaling, applications of chiral perturbation theory, non-perturbative renormalization and finite volume effects. Additionally, the importance of demonstrati...

We consider the Schrödinger functional with staggered one-component fermions on a fine lattice of size (L/a)3 × (T/a) where T/a must be an odd number. In order to reconstruct the fourcomponent spinors, two different set-ups are proposed, corresponding to the coarse lattice having size (L/2a)3 × (T ′/2a), with T ′ = T ± a. The continuum limit is then defined at fixed T ′/L. Both cases have previ...

We investigate what can be learnt about the η -η mixing by means of dispersive representation of axial anomaly. We show that our method leads to the strong bounds for the η − η mixing angle: θ = −15.3◦ ± 1. Moreover, our result manifests also a dramatic dependence of the width Γη→2γ on the mixing angle θ. This property explains how the relatively small mixing strongly effects the decay width.
