Strange Electromagnetic Form Factors of the Nucleon with Nf=2+1 O(a) -Improved Wilson Fermions

Autor: Jonas Wilhelm, Hartmut Wittig, Dalibor Djukanovic, Konstantin Ottnad

Publikováno v: Physical Review Letters. 123

We present results for the strange contribution to the electromagnetic form factors of the nucleon computed on the coordinated lattice simulation ensembles with N_{f}=2+1 flavors of O(a)-improved Wilson fermions and an O(a)-improved vector current. S

Strange nucleon form factors with $N_f=2+1$ O($a$)-improved Wilson fermions

Autor: Konstantin Ottnad, Dalibor Djukanovic, Georg von Hippel, Hartmut Wittig, Jonas Wilhelm, Harvey B. Meyer

Publikováno v: Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018).

We present preliminary results for strangeness form factors of the nucleon computed on the CLS ensembles with $N_f=2+1$ flavors of O($a$)-improved Wilson fermions. Our calculations are performed at two values of the lattice spacing ($a \in \{0.064, 0

We present a lattice calculation of the nucleon iso-vector axial and induced pseudoscalar form factors on the CLS ensembles using $N_{\rm f}=2$ dynamical flavours of non-perturbatively $\mathcal{O}(a)$-improved Wilson fermions and an $\mathcal{O}(a)$

We revisit the problem of deriving local gauge invariance with spontaneous symmetry breaking in the context of an effective field theory. Previous derivations were based on the condition of tree-order unitarity. However, the modern point of view cons
