متن کاملDecay constants from twisted mass QCD
We present results for chiral extrapolations of the mass and decay constants of the rho meson. The data sets used are the n f =2 unquenched gauge configurations generated with twisted mass fermions by the European Twisted Mass Collaboration. We describe a calculation of three decay constants in charmonium and explain why they are required. Decay constants from twisted mass QCD.
متن کاملContinuum limit of the spectrum of the hadronic string
We look at the continuum limit of the two universal predictions of the hadronic string theory namely the Lüscher term and the energy difference between successive energy states in three dimensional SU(2) lattice gauge theory using Wilson loops and Polyakov loop correlators. We also compare our simulation data with the theoretical predictions in [10].
متن کاملThe continuum limit of the static - light meson spectrum
We investigate the continuum limit of the low lying static-light meson spectrum using Wilson twisted mass lattice QCD with Nf = 2 dynamical quark flavours. We consider three values of the lattice spacing a ≈ 0.051 fm , 0.064 fm , 0.080 fm and various values of the pion mass in the range 280MeV ∼mPS ∼ 640MeV. We present results in the continuum limit for light cloud angular momentum j = 1/2 , 3/...
متن کاملLight Quenched Hadron Spectrum and Decay Constants on different Lattices
In this paper we study O(2000) (quenched) lattice configurations from the APE collaboration, for different lattice volumes and for 6.0 ≤ β ≤ 6.4 using both the Wilson and the SW-Clover fermion actions. We determine the light hadronic spectrum and meson decay constants and study the mesonic dispersion relation. We extract the hadronic variable J and the strange quark mass in the continuum at the...
