abstract
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, all of them for the nucleon. A detailed error analysis for each observable follows, showing the strengths and weaknesses of the one-end trick. Alternatives are discussed.

Nucleon charges and $\sigma$-terms in lattice QCD
First-principles lattice QCD at the physical pion mass yields nucleon charges and sigma-terms in the continuum limit, with g_A^{u-d}=1.250(24) matching experiment.
