Parton Distribution Functions with Twisted Mass Fermions
S. Capitani, K. Jansen, M. Papinutto +3
We present a first Wilson twisted mass fermion calculation of the matrix element between pion states of the twist-2 operator, which is related to the the lowest moment < x > of the…
3-point functions from twisted mass lattice QCD at small quark masses
S. Capitani, K. Jansen, M. Papinutto +3
We show at the example of the matrix element between pion states of a twist-2, non-singlet operator that Wilson twisted mass fermions allow to compute this phenomenologically relev…
Twisted mass fermions: neutral pion masses from disconnected contributions
F. Farchioni, K. Jansen, C. McNeile +12
Twisted mass fermions allow light quarks to be explored but with the consequence that there are mass splittings, such as between the neutral and charged pion. Using a direct calcul…
Flavour Breaking Effects of Wilson twisted mass fermions
K. Jansen, C. McNeile, C. Michael +6
We study the flavour breaking effects appearing in the Wilson twisted mass formulation of lattice QCD. In this quenched study, we focus on the mass splitting between the neutral an…
Quenched Scaling of Wilson twisted mass fermions
K. Jansen, M. Papinutto, A. Shindler +2
We investigate the scaling behaviour of quenched Wilson twisted mass fermions at maximal twist applying two definitions of the critical mass. The first definition uses the vanishin…
Lattice Spacing Dependence of the First Order Phase Transition for Dynamical Twisted Mass Fermions
F. Farchioni, K. Jansen, I. Montvay +7
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…
