Disconnected diagrams with twisted-mass fermions
(Proceedings of Science (PoS), 2016)The latest results from the Twisted-Mass collaboration on disconnected diagrams at the physical value of the pion mass are presented. In particular, we focus on the sigma terms, the axial charges and the momentum fraction, ...

Hadron structure in lattice QCD
(2012)Recent progress in hadron structure calculations within lattice QCD is reviewed. Results on key observables such as the axial charge, the quark momentum fraction and the spin content of the nucleon are discussed with focus ...

Nucleon generalized form factors with twisted mass fermions
(Proceedings of Science (PoS), 2013)We present results on the nucleon form factors, momentum fraction and helicity moment for Nf = 2 and Nf = 2+1+1 twisted mass fermions for a number of lattice volumes and lattice spacings. First results for a new Nf = 2 ...

Nucleon spin and quark content at the physical point
(Proceedings of Science (PoS), 2016)We present results on the spin and quark content of the nucleon using Nf =2 twisted mass cloverimproved fermion simulations with a pion mass close to its physical value. We use recently developed methods to obtain accurate ...
