Lattice Spacing Dependence of the First Order Phase Transition for Dynamical Twisted Mass Fermions
نویسنده
چکیده
Lattice QCD with Wilson fermions generically shows the phenomenon of a first order phase transition. We study the phase structure of lattice QCD using Wilson twisted mass fermions and the Wilson plaquette gauge action are used in a range of β values where such a first order phase transition is observed. In particular, we investigate the dependence of the first order phase transition on the value of the lattice spacing. Using only data in one phase and neglecting possible problems arising from the phase transition we are able to perform a first scaling test for physical quantities using this action.

The phase diagram of twisted mass lattice QCD
We use the effective chiral Lagrangian to analyze the phase diagram of two-flavor twisted mass lattice QCD as a function of the normal and twisted masses, generalizing previous work for the untwisted theory. We first determine the chiral Lagrangian including discretization effects up to next-to-leading order (NLO) in a combined expansion in which m2π/(4πfπ) 2 ∼ aΛ (a being the lattice spacing, ...
متن کاملTwo–dimensional lattice Gross–Neveu model with Wilson twisted mass fermions
We study the two-dimensional lattice Gross–Neveu model with Wilson twisted mass fermions in order to explore the phase structure in this setup. In particular, we investigate the behaviour of the phase transitions found earlier with standard Wilson fermions as a function of the twisted mass parameter μ. We find that qualitatively the dependence of the phase transitions on μ is very similar to th...
متن کاملOverlap fermions on a twisted mass sea
We present first results of a mixed action project. We analyze gauge configurations generated with two flavors of dynamical twisted mass fermions. Neuberger’s overlap Dirac operator is used for the valence sector. The various choices in the setup of the simulation are discussed. We employ chiral perturbation theory to describe the effects of using different actions in the sea and valence sector...
متن کاملChiral perturbation theory for twisted mass QCD
Quantum Chromodynamics on a lattice with Wilson fermions and a chirally twisted mass term for two degenerate quark flavours is considered in the framework of chiral perturbation theory. The pion masses and decay constants are calculated in next-to-leading order including terms linear in the lattice spacing a. We treat both unquenched and partially quenched QCD. We also discuss the phase structu...
متن کاملDynamical lattice QCD thermodynamics with domain wall fermions
We present results from simulations of two flavor QCD thermodynamics at Nt = 4 with domain wall fermions. In contrast to other lattice fermion formulations, domain wall fermions preserve the full SUL(Nf )⊗ SUR(Nf) symmetry of the continuum at finite lattice spacing (up to terms exponentially small in an extra parameter). Just above the phase transition, we find that the UA(1) symmetry is broken...
