M ay 1 99 8 1 Improved Lattice Actions with Chemical Potential
We give a prescription how to include a chemical potential µ into a general lattice action. This inclusion does not cause any lattice artifacts. Hence its application to an improved – or even perfect – action at µ = 0 yields an improved resp. perfect action at arbitrary µ. For short-ranged improved actions, a good scaling behavior holds over a wide region, and the upper bound for the baryon den...
متن کاملImproved lattice actions
The idea to improve lattice actions [1,2] is nearly as old as the use of lattices in regularizing field theories [3]. Nevertheless, until recently numerical simulations were performed mostly with the simplest (standard) form of lattice actions. This attitude seems to have been altered — at this conference there were probably more contributions using some kind of improved action than the standar...
متن کاملLattice Simulations with Chemical Potential
After giving an overview of recently invented methods for simulating lattice QCD at small µ/T , we discuss some results for bulk thermodynamic quantities of QCD matter coming from those methods. We focus on the transition line and the critical endpoint in the QCD phase diagram.
متن کاملGlueballs from Improved Lattice Actions
Glueballs and hybrid mesons are presently of great interest theoretically and experimentally. The lattice formulation of QCD provides an ideal setting in which to carry out theoretical studies of such systems from first principles using sophisticated numerical simulations. In order to extract the physical properties of glueballs and hybrid mesons from such simulations, systematic errors from th...
متن کاملImproved Lattice Qcd Actions for Hadron Phenomenology
The masses and dispersions of light hadrons are calculated in lattice QCD using an O(a) tadpole-improved gluon action and the Dχ34 action, an O(a) tadpoleimproved next-nearest-neighbor fermion action originally proposed by Hamber and Wu. Two lattices of constant volume with lattice spacings of approximately 0.40 fm and 0.24 fm are considered. The results reveal some scaling violations at the co...
