Baryon masses with dynamical twisted mass fermions
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 lattice spacings a(β = 3.9) = 0.0855(6) fm...
متن کاملNucleon and Delta masses in twisted mass chiral perturbation theory
We calculate the masses of the nucleons and deltas in twisted mass heavy baryon chiral perturbation theory. We work to quadratic order in a power counting scheme in which we treat the lattice spacing, a, and the quark masses, mq, to be of the same order. We give expressions for the mass and the mass splitting of the nucleons and deltas both in and away from the isospin limit. We give an argumen...
متن کاملStatic-light meson masses from twisted mass lattice QCD
We compute the static-light meson spectrum using two-flavor Wilson twisted mass lattice QCD. We have considered five different values for the light quark mass corresponding to 300 MeV < ∼ m PS < ∼ 600 MeV. We have extrapolated our results, to make predictions regarding the spectrum of B and B s mesons.

متن کاملCosmology with twisted tori
We consider the cosmological role of the scalar fields generated by the compactification of 11dimensional Einstein gravity on a 7-dimensional elliptic twisted torus, which has the attractive features of giving rise to a positive semidefinite potential, and partially fixing the moduli. This compactification is therefore relevant for low-energy M-theory, 11-dimensional supergravity. We find that ...
