Comparing Wilson and Clover quenched SU(3) spectroscopy with an improved gauge action

چکیده
We present results of quenched SU(3) hadron spectroscopy comparing O(a) improved Wilson (Clover) fermions with conventional Wilson fermions. The configurations were generated using an O(a) improved 6-link SU(3) pure gauge action at β’s corresponding to lattice spacings of 0.15, 0.18, 0.20, 0.33, and 0.43 fm. We find evidence that fermionic scaling violations are consistent with O(a) for Clover and O(a) with a nonnegligible O(a) term for standard Wilson fermions. This latter mixed ansatz makes a reliable continuum extrapolation problematic for Wilson fermions. We also find that the slope of the scaling violations is roughly 250MeV for both Wilson and Clover fermions.

Reducing Discretization Errors in Lattice Qcd Spectroscopy
The improved Wilson quark action – the clover action – is constructed to have smaller discretization errors than the normal Wilson quark action. We test this in a quenched spectroscopy computation on 6 lattice ensembles with spacings from 0.15 to 0.43 fm. To ensure that the dominant scaling violations come from the fermions we use an O(a) improved 6-link SU(3) pure gauge action. We find evidenc...
متن کاملQuenched SU(3) hadron spectroscopy using improved fermionic and gauge actions
The Symanzik action improvement program has been proposed [1,2] as a way to reduce scaling violations in the approach to the continuum limit from a lattice action. In another contribution, we report on our preliminary investigations into the nature of scaling violations inherent in improved actions. In another proceedings in this volume[4], we make detailed comparisons of Wilson and tadpole-imp...
متن کاملTests of Hypercubic Fermion Actions
I have performed scaling tests using quenched spectroscopy of a family of fermion actions which have a hypercubic kinetic term, gauge connections built of smeared links, and an anomalous magnetic moment term. These actions show improved rotational invariance compared to the standard Wilson action and to the tadpole-improved clover action. Hyperfine splittings are improved compared to the standa...
متن کاملQuenched Light Hadron Spectroscopy: Comparing the Wilson and O(a)-Improved Fermion Actions
We have studied the light hadron spectrum and decay constants for quenched QCD at β = 6.2 on a 24 × 48 lattice. We compare the results obtained using a nearest-neighbour O(a)-improved (“clover”) fermion action with those obtained using the standard Wilson fermion action on the same gauge configurations. For pseudoscalar meson masses in the range 330-800 MeV, we find no significant difference be...
متن کاملInvestigating and Optimizing the Chiral Properties of Lattice Fermion Actions
We study exceptional modes of both the Wilson and the clover action in order to understand why quenched clover spectroscopy suffers so severely from exceptional configurations. We show that, in contrast to the case of the Wilson action, a large clover coefficient can make the exceptional modes extremely localized and thus very sensitive to short distance fluctuations. We describe a way to optim...
