Exploring the phase structure of lattice QCD with twisted mass quarks

F. Farchioni, C. Urbach, R. Frezzotti +7

The phase structure of zero temperature twisted mass lattice QCD is investigated. We find strong metastabilities in the plaquette observable when the untwisted quark mass sweeps ac…

Chirally improving Wilson fermions II. Four-quark operators

R. Frezzotti, G. C. Rossi

In this paper we discuss how the peculiar properties of twisted lattice QCD at maximal twist can be employed to set up a consistent computational scheme in which, despite the expli…

Twisted mass quarks and the phase structure of lattice QCD

F. Farchioni, R. Frezzotti, K. Jansen +7

The phase structure of zero temperature twisted mass lattice QCD is investigated. We find strong metastabilities in the plaquette observable when the untwisted quark mass assumes p…

Non-perturbative renormalization of lattice operators in coordinate space

V. Gimenez, L. Giusti, S. Guerriero +6

We present the first numerical implementation of a non-perturbative renormalization method for lattice operators, based on the study of correlation functions in coordinate space at…

Twisted mass QCD and lattice approaches to the rule

C. Pena, S. Sint, A. Vladikas

Twisted mass lattice QCD (tmQCD), generalised to four Wilson quark flavours, can be used for the computation of some weak matrix elements related to transitions. Besides e…

The continuum limit of the quark mass step scaling function in quenched lattice QCD

M. Guagnelli, J. Heitger, F. Palombi +2

The renormalisation group running of the quark mass is determined non-perturbatively for a large range of scales, by computing the step scaling function in the Schroedinger Functio…

Finite size effects of a pion matrix element

M. Guagnelli, K. Jansen, F. Palombi +3

We investigate finite size effects of the pion matrix element of the non-singlet, twist-2 operator corresponding to the average momentum of non-singlet quark densities. Using the q…

Topological susceptibility in full QCD with Ginsparg-Wilson fermions

L. Giusti, G. C. Rossi, M. Testa

We show that, if the formula for the topological charge density operator suggested by fermions obeying the Ginsparg-Wilson relation is employed, it is possible to give a precise an…
