Abstract We investigate the continuum spectrum of the SU(2) gauge theory with N f = 2 flavours of fermions in the fundamental representation. This model provides a minimal template which is ideal for a wide class of Standard Model extensions featuring novel strong dynamics that range from composite (Goldstone) Higgs theories to several intriguing types of(More)
We present results on the mass of the nucleon and the ∆ using two dynamical degenerate twisted mass quarks. The evaluation is performed at four quark masses corresponding to a pion mass in the range of 690-300 MeV on lattices of size 2.1 fm and 2.7 fm. We check for cutoff effects by evaluating these baryon masses on lattices of spatial size 2.1 fm with(More)
We present results on the mass of the baryon octet and decuplet using two flavors of light dynamical twisted mass fermions. The strange quark mass is fixed to its physical value from the kaon sector in a partially quenched set up. Calculations are performed for light quark masses corresponding to a pion mass in the range 270-500 MeV and lattice sizes of 2.1(More)

We perform a lattice computation of the flavour octet contribution to the average quark momentum in the nucleon, 〈x〉 μ2=4 GeV2 . In particular, we fully take the disconnected contributions into account in our analysis for which we use a generalization of the technique developed in [1]. We investigate systematic effects with particular emphasis on the(More)
The paper is concerned with some data, obtained during a study of case histories and x-ray findings of 12 (0.1%) of 9260 patients treated over the last 10 years in a traumatology department at a regional hospital for various traumas. Posttraumatic oil embolism was diagnosed in these 12 patients during their life. Of them 2 patients were women, and 10 men(More)
We present a stochastic method for the calculation of baryon three-point functions that ismore versatile than the typically used sequential method. We analyze the scaling of the error of the stochastically evaluated three-point function with the lattice volume, and we found a favorable signal-to-noise ratio suggesting that our stochastic method can be used(More)
