Nucleon axial and pseudoscalar isovector form factors from lattice QCD
Autor: Wurm, Thomas
The axial structure of the nucleon, in particular the iso-vector axial and (induced) pseudoscalar form factors, can be analyzed from first principles using Monte Carlo techniques in lattice QCD. Effective field theory predicts that pseudoscalar form

Physical Review
We evaluate all two-point correlation functions of the Curci-Ferrari (CF) model in four dimensions and in the presence of mass-degenerate fundamental quark flavors, as a natural extension of an earlier investigation in the quenched approximation. In

Two of the elements of the Cabibbo-Kobayashi-Maskawa quark mixing matrix, $|V_{ub}|$ and $|V_{cb}|$, are extracted from semileptonic B decays. The results of the B factories, analysed in the light of the most recent theoretical calculations, remain p

Quark and Polyakov-loop correlations in the Polyakov-Nambu-Jona-Lasinio model
Autor: Hansen, Hubert, Stiele, Rainer, Costa, Pedro
The aim of this work is to shed light to some less known aspects of Polyakov-loop extended chiral models, especially on the correlation of the quark sector and the Polyakov loop. We show that the order of chiral and Polyakov-loop transition and their

Within the framework of chiral effective field theory we discuss the leading contributions to the neutrinoless double-beta decay transition operator induced by light Majorana neutrinos. Based on renormalization arguments in both dimensional regulariz
